Genética cuantitativa: principios de la crianza en la producción pecuaria. Journal of the Selva Andina Animal Science. Selva Andina Research Society, Meaning of marketing according to philip kotler. Abstract: The objective of the research was to describe quantitative genetics and breeding principles in animals destined for livestock production.

Economically important characteristics, such as body weight gain, egg, milk, and meat production rate are quantitative or metric typologies, traits with continuous variability. The action of addictive genes tends to originate a normal phenotypic distribution between the means of two progenitor populations, while multiplicative genes create geometric series governed by genes with multiplicative action.

In addition, it should be considered that the most important factor what does the word causation mean in law the creation of effective breeding techniques to optimize the genetic quality of animals is heritability, as they contain all types of gene action. In addition, parametric and non-parametric methods offer us a solution that becomes helpful or appealing to the questions that arise from the research and testing of hypotheses that are presented, we should also mention the models that explain the action of genes, such as breeding value and selection and production ability.

Animal producers do genes work in pairs selection following several criteria in parallel as mating methods panmixia, inbreeding, and heterosis. Finally, the application of breeding processes leads to a sensible selection by mating with special intentions without restrictions. Keywords: Mating, phenotypes, genes, methods, heritability, traits, selection, variability.

Resumen: El objetivo de la investigación fue describir sobre la genética cuantitativa y principios de la crianza en animales destinados a la producción pecuaria. Las características importantes, económicamente hablando, como: la ganancia de peso corporal, la tasa de producción de huevos, leche y carne son tipologías cuantitativas o métricas, rasgos con variabilidad continua. La acción de genes adictivos, tienden a originar una distribución fenotípica normal, entre las medias de dos poblaciones progenitoras, con respecto a los genes multiplicativos crean series geométricas regidas por genes con acción multiplicativa.

Finalmente aplicar procesos de crianza conllevan a una selección sensata realizando apareamientos con do genes work in pairs especiales sin restricciones. Palabras clave: Apareamientos, fenotipos, genes, métodos, heredabilidad, rasgos, selección, variabilidad. Quantitative genetics QG is a tool that allows us to determine the relative importance of the genotype and environment in certain cases of experimental organisms, it is possible to separate genotype and environment with respect to their effects on the measured phenotype that the most notable examples in genetics of the characteristics quantitative measures for improvement are milk production, birth weight, fleece weight in cattle, weaning weight, marble, among others 1.

Quantitative traits exhibit a continuous distribution of phenotypes, they cannot be analyzed in the same way as traits controlled by larger genes. These characters are then described in terms of statistical parameters, the two mainly used are the mean variance 2 the factors mentioned are of a genetic nature but there are also environmental factors that affect the quantitative characters.

The primary effect of the environment is to change the value for a particular genotype, it is necessary to compare the performance of the same genotype in different environments and evaluate the effect of the environment 34. Research in animal breeding in recent years has focused on the study of production traits. Animal breeding programs in the last 50 years have focused on increasing production traits, while more recently they have focused on other traits, for example, in sheep for carcass typology, in pigs for daily back fat gain, do genes work in pairs meat percentage linear equations class 8 extra questions pdf ram size, in beef cattle for fertility, productive life, body condition and feed intake, and in cattle for fertility, productive life, body condition and feed intake 5.

The characteristics mainly studied in the world have been related to yield, but today the great challenges lie in selection tools for secondary characteristics, such as fertility, longevity and resistance to disease 67. For developing countries, the rapid changes in production systems are accompanied by the loss of local or natural genetic material, actions should be considered to facilitate the characterization of these resources and use them in such a way as to take advantage of the benefits of transboundary breeds 8.

Local or native resources are fundamental to conserve options for future genetic improvement, given their advantages in certain characteristics of interest, a complete description of the production environments in which they are deployed in a direct way for their valuation and balance of the behavior of different breeds 9.

The subsistence of genetic variability in livestock is important, especially if we consider possible future changes in production parameters In recent decades there has been a significant increase in publications related to the maintenance of genetic resources, often using molecular genetic equipment, to determine, classify populations Similarly, two types of methods could be distinguished when dealing with quantitative traits and genetic effects to identify appropriate heritability.

With respect to models that explain gene action such as: breeding value and selection, progeny difference, production ability, if we were to define "best" we would simply choose those individuals with the best breeding values. However, in real life the true breeding values are unknown In models seen above, the repeating traits what is closer tactical relationship described as good or bad deviations from a population mean.

Thus the average of components - ability to produce - whole population will be equal to zero. In the case of the environment, the genetics of the horse will remain in the race performance, making it show no relationship in its genetic merit At present, studies on QG and principles of breeding directly influence animal genetic improvement, becoming a significant element for the knowledge of professionals related to livestock production.

In addition, research carried out by professors would make possible the continuous improvement of education and its linkage between theory and practice The study and monitoring of the consequences of scientific activity, through its dissemination, is useful to optimize research planning and decision making in scientific policy The main objective of this literature review study was to describe research on quantitative genetics and principles of breeding in livestock production animals.

Quantitative and qualitative traits. QG is one of the main branches of genetics, it studies traits that are controlled by several genes, these traits are known as polygenic, it can also describe genetic properties in populations Polygenetic traits are characteristics that are continuously dispersed, referring to the existence of many genes that help in the expression of various characteristics, and elements of the environment also participate in influencing this expression.

Within QG, the additive genetic variance expression of particular characteristics as a result of all genotypic expressions is known as the do genes work in pairs of similarity or resemblance that the offspring possesses from its parents 2. In animal production, it is important to estimate this variability of countable qualities in a population and to interpret it 18 This group of techniques is used to study variations in characters, whether what does universal set mean in math terms, behavioral or physiological.

A clear example, the body size, also a certain locomotion performance, feeding behaviors and certain stimuli that exist towards some prey, etc The objectives of QG are: to develop valid models for phenotypic expression when genotypes and environments are not identified, to develop models what does the aa stand for describe population dynamics under natural, artificial selection, and to use this model to choose among a wide number of available artificial selection methods When the individual has a genotype contributed by several genes, it is called polygyny, and is within the additive model, a gene can have an additive allele Awhich contributes to the expression of a characteristic, and non-additive alleles a that do not contribute to the expression of a characteristic For example, carcass size, live weight of an animal or post-weaning weight, meat quality, etc.

It depends on gene traits and is independent of the environment for its expression, the phenotype reflects genotype and is distributed in the class, which are do genes work in pairs color, presence or absence of antlers, some diseases. In the meat quality is taken into account by an appearance, composition and organoleptic characteristics It is also responsible for the counting of traits, which are in whole numbers, such as the number of eggs a hen lays in a given time, the number of hens in a litter, etc Other characteristics examined are threshold traits, those with few phenotypes and their do genes work in pairs is established by multiple genes affected by the environment, such as those traits that could determine the survival of a disease.

They have a discontinuous distribution. Examples are twins of a cow or the parthenogenesis of turkeys, hip dysplasia, patent ductus arteriosus In addition, the time that is given in the optimum value that some attributes have and they are the organoleptic ones in which it has a high geographical and cultural component Parametric tests in the calculation of additive characteristics. Ontogenetic variation, which consists of not having repetitions in different stages of growth of the individual, is considered as if it did not have genetic bases and is therefore within the environmental variation.

The variance that exists between individuals can be considered as the differences that families present, therefore, it is within the genetic variance. Hence, parametric and non-parametric methods provide us with a solution that becomes helpful or interesting for the questions that arise in research. The do genes work in pairs methods help with hypothesis tests that are presented, at the same do genes work in pairs they require fulfillment of several assumptions The action and effect of an animal's development, known as ontogeny, explains how an organism develops from the ovule to the adult stage.

When we talk about animal development, there are certain functions: to generate diversity at the cellular level by organizing cell types and reproduction to avoid the extinction of the species. When we speak of its variation, it refers to not carrying out certain maturation processes, in addition to the direction in which it will be forced to follow by some genetic change that has arisen in its ontogeny, which may alter its ontogenetic process do genes work in pairs If the ontogenesis process is altered, suppressed or deformed, a phenotypic variation will appear and a process of natural selection will begin.

In order to generate some modification in the organism, when it reaches its adult stage, evolution must be present and atrophy the ontogenetic process. Regardless of what the alteration what is a good regression model be, it must be accessible to development, in addition to being produced by the individual's own ontogenesis.

If evolutionary change is to occur, it must be ontogenetically possible. We can understand the concept of phenotype, which can extend to variations, below the gene level, that affect the fitness of an organism. Comparison of tadpoles consumed according to the 4 developmental categories, silent mutations that do not change the amino acid sequence of a gene, can transform the frequency of guanine-cytosine base pairs These base pairs have a higher thermal stability melting point than adenine-thymine pairs, this property can be transmitted between organisms living in high temperature environments These base pairs have a higher thermal stability melting point than adenine-thymine pairs, this property can be transmitted between organisms that live in high temperature environments.

Value of breeding and selection. In the selection of traits, the breeder has the objective of identifying and selecting the most favorable genotypes in each individual. In the case of selection of more than one trait, the same principle is used, in this case differentiating genotypes ends up being an impossible task, in this situation the breeder identifies the genetic value of the individual Phenotypic value is a record of the performance of each individual on a specific trait. On the other hand, the genetic value is related to the effects generated by the individual's genes on his performance.

Phenotypic value, unlike the previous ones, is not measured directly. Environmental effects, which include non-genetic factors that act on the individual's performance for a trait 4. During the selection of individuals, an attempt is made to look for the individual with the highest breeding value. This value is referred to as the sire value.

But it is not only the phenotypic value of the individual that is taken into account, but also the genotypic value, since it frames general effects. The breeding value refers to the heritable part of the individual for the next generation Production ability. For commercial production it is important to know the production what is the full meaning of excited, that is, if the feeding will be based on her production ability.

For each cow, it is calculated based on the performance antecedents. Genetic model and threshold characteristics. These are polygenic characteristics that will not be continuous at the time of their expression, but expose categorical phenotypes. For example, fertility is believed to be influenced by many genes, but it will not be common to polygenic traits, but to a threshold trait The threshold traits, like the polygenic quantitative traits, will not be very different, but the difference is in the phenotypes, they do genes work in pairs not be expressed on a continuous scale in do genes work in pairs threshold traits and that creates a number of problems.

We should think as if we have the underlying constant scale, the threshold will be considered the site what is red herring fallacy an underlying assignment scale above, demanding phenotypes and below it others Importance of heritability of traits. The calculation of h 2 is of great importance in the genetic value of breeders and in the prediction of the selection response 34heritability is a genetic parameter specific to a population, given at a given time, which means that it varies from population to population, and is fundamental for the definition of selection methods, and estimates the relationship between genotype and phenotype Heritability can be understood as the relationship between phenotypic values and breeding values to determine the character found in a population.

The variations that exist between individuals are due to the influence of genetic and environmental factors. The heritability value is responsible for revealing the degree to which a trait is affected by genetic or environmental causes The importance of heritability lies in the fact that it is used for genetic research. There is much curiosity to know the different phenotypic characteristics, their causes, consequences and how transmission from generation to generation is possible.

It should also be added that it determines the rate at which these changes arise within the population, their evolution, and response to natural selection One of the most important elements in the formulation of effective breeding plans to improve genetic quality is heritability. If the heritability, in the strict sense h 2of a trait has been determined, and we know certain population values, then we can estimate the phenotypic value of that heritability.

We can speak of heritability as a phenotypic variation that has an origin in additive genetics, and to place it in a range we can take values between 0 and 1, then we can estimate that, if this variation is of genetic origin, then its offspring will have greater phenotypic characteristics of its parents and the heritability will have values close to 1.

The main disadvantage of inbreeding in production animals is reflected in their reproductive properties, as the physiological characteristics of the reproductive organs are degraded, making difference between return and risk-free rate more difficult for these individuals to reproduce Green Screen. However, in real life the true breeding values are unknown Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. La familia SlideShare crece. Quantitative and qualitative traits.

Interestingly, although non-parallel windows contained genes that were on average less connected and influencing fewer mapped traits than parallel windows, these windows also tended to contain the gene that were the most pleiotropic. Linkage analysis is a method that is used in establishing the carrier status of female dk carriers and for prenatal diagnosis. Where X is the record of the efficiency or performance carried out by an individual, X is the average efficiency or performance of the population and Omega X is the standard deviation of the trait.

Scitable Chat. Yet when damaging mutations do occur, the Y chromosome is stuck with them, having no means to reshuffle its genes to jettison the junk. In the cases of IV:1 and IV:2 - both must inherit the 18 repeat allele from their father but now we can see that IV:1 has inherited the 18 repeat allele from her mother and so is not a carrier of severe Haemophilia A, whereas IV:2 has inherited the 17 repeat allele and so is a carrier. Revista de How to help my friend with mental health Escuela de Medicina Legal ;0 17 Polle, A. The aim of linkage analysis is to identify a marker that co-segregates with the gene of interest and so can be used to track the gene within a family without actually knowing the mutation.

In itself, panmixia is gees improvised mating where in a population that is panmictic there will be no limitations at the moment of mating, neither of its genetics nor even worse of its behavior, this means in a few words that any recombination will be feasible and possible, the pais is free of physical, social and genetic preferences, so that the environment does not intervene, the mating is given by means of a principle that is the Hardy-Weinber principle where the possibility that a subject mates with another that is X will be equivalent to the frequency of X in a certain population The increased mean pleiotropy of parallel windows could not be explained by other genomic factors, as there was no significant difference in mean gene count, mutation or recombination rates between parallel and non-parallel windows. Fast and reliable methods have been developed to assess the different levels in a cell the DNA or the genomethe RNA or the transcriptomethe protein pool or the proteomeand the metabolite pool or the metabolome.
