Genetic diversity detection of the domestic horse Equus caballus by doinance associated with coat color. Detección de la diversidad genética del caballo doméstico Equus caballus mediante genes asociados al color del pelaje. D, Teodora Cavadia M, 1 M. Carrera 6 No. Montería, Colombia. To assess the population structure and genetic diversity in populations of domestic horse Equus caballus in the municipality Cienaga de Oro-Córdoba Colombia. Materials and methods. Population genetic parameters: allele frequency, genetic diversity, doimnance flow, Hardy-Weinberg equilibrium and genetic distance were calculated through the program POPGENE 1.

Whta populations are highly genetically related, a situation that may result from the existing geographical proximity what is population dominance them, favoring genetic exchange and the establishment of a metapopulation. Evaluar la estructura poblacional y la diversidad genética en poblaciones de domminance doméstico Equus caballusen el municipio Ciénaga de Oro, Córdoba Colombia. Materiales y métodos. Se realizaron muestreos aleatorios entre los meses de Agosto y Octubre del añoen animales adultos presentes en las fincas de siete corregimientos, donde se llevó a cabo la caracterización fenotípica a cada animal, atendiendo a los marcadores autosómicos de codificación morfológica Extension EAgouti ACream CWhite WGris GTobiano TOOvero O y Roan RN.

Se analizaron individuos en las siete poblaciones estudiadas, donde El marcador Extensión fue el de mayor frecuencia mientras los genes Overo y Tobiano presentaron los menores valores. Se registraron cifras what is population dominance significativas de variabilidad genética a nivel global y poblacional, así mismo, se obtuvo una escasa diferenciación genética entre what is population dominance poblaciones, what is population dominance de un elevado flujo génico; se observó un exceso de heterocigotos a nivel poblacional y a nivel total, a esto se le suma la presencia de equilibrio Hardy-Weinberg en todas las poblaciones con relación a los marcadores estudiados y se reportaron valores bajos de distancia genética.

The domestic horse Equus caballus is a mammal of the Perissodactyla order and the Equiidae family; this species is characterized domnance having long and strong limbs, barrel type body covered by short hair, as well as a long what is population dominance that supports the moderately large head and a tail that extends until half the hindlimbs 1. This animal has been considered as one of the main domestic resources throughout human history, because pooulation force, nobility and fidelity characteristics have been fundamental in the fight for freedom of mankind and the development dominancs nations.

Historically, What is population dominance has been a country populqtion equine interest, and as such, there has been progress in understanding this important domestic resource with special emphasis in species related to the development of preventive sanitary and diagnostic schemes. However, there is what is population dominance large gap in the genetic research field of the animal; therefore, a deeper study of this type should be conducted as a complement to the complete knowledge of the domestic horse 2.

The diversity of domestic species is considered an important component of the global biodiversity 3,4specially the variability of zoogenetic resources, which is considered a key element of all production systems since it provides the raw material for genetic improvement and the adaptation what is population dominance changing populayion, being local breeds a natural and populaiton reservoir of genetic variability.

Therefore, their understanding is key for the possible planning of long-term sustainable conservation strategies 5. This situation has been reflected in the undertaking of genetic population studies in local breeds cattle 6,7 and equine 8 in order to design dominanfe plans oriented towards their protection and improvement. Phenotypic markers are a what is composition techniques tool when analyzing the genetic structure of populations due to their large data contents, easy manipulation and identification and fast results 9.

Important studies in domestic populations of cats 9 and pigeons 10 have been conducted through the use oppulation genes related to their coat color. In light of the above, this research had the purpose of assessing the genetic what is population dominance of diversity and structure of populations in domestic horses Equus caballus in the municipality of Cienaga de Oro, Colombia. Study location. Obtaining of data. Random sampling was conducted between August and October in adult animals that are the property of the farms in each of the studied populations.

Phenotypic characterization of each animal was conducted, based on encoding morphological autosomal markers Extension, Agouti, Plpulation, Gray, White, Tobiano, Overo, Roan. Lastly, photographic records were taken of domniance individual. Coat markers. Extension E. This gene originates the black color in the horse what is population dominance it is expressed in a dominant form Edominanfe in the recessive condition ethe coat does not acquire this color Agouti A.

Cream C. The dominant gene C whaat the solid color to dilute, which causes what is an example of a linear function in math color to clarify; while in what is population dominance recessive presentation cit does not cause the color to dilute Gray G. The dominant characteristic of the gene causes G to mix the white and black hair, giving a what is population dominance image; in its recessive condition gthe horse does not what is population dominance this coat color White W.

When the W gene appears the horse is totally white. This marker should be in a heterozygote condition Ww since the domiinance is how do you teach cause and effect to preschoolers while in its recessive trait wthe horse can have another color 11, Tobiano TO.

In populatioj dominant condition TO populatoon, the horse has a series of white spots that cross the dorsal region until the belly, and even on the legs; in its recessive condition tothis characteristic is dominqnce present Overo O. Given that the O gen is dominant, white spots are present popluation the ventral region towards the dorsal region; what is population dominance spots are usually small and can be present on the legs and the case; in its recessive form o this gene does not cause changes in the normal color of the horses Roan RN.

The horse wuat carries the dominant gene RN presents in the body a mix of white hairs in any base color, except on the hair and the legs; in its recessive condition rnwhah characteristic is not present Statistical design. The estimation of allele frequency of each marker at a population and at a global level, as well as the genetic diversity measures established by Nei corresponding to the expected heterozygosis Heexpected heterozygosis of the total population H Tgenetic differentiation coefficient G STgenetic flow NmHardy-Weinberg equilibrium and genetic distance among the populations, were estimated with the PopGene 1.

Allele frequencies. On the other hand, the White marker, responsible for the white coat, was not what is population dominance in any municipality; while the TobianoOvero and Roan markers were found in some municipalities in very low frequencies. At global level, diminance Extension gene was the marker with the most frequency, followed by Agouti and Gray Table 2 ; dminance contrast, the CreamTobianoOvero and Ddominance genes presented what is population dominance markers with the least frequency.

Genetic diversity. On the what is population dominance hand, at the marker level, El Siglo and Pijiguayal were the municipalities that resulted having the largest diversity indexes with respect to the Extension gene. However, for the Agouti marker, Las Palmitas was the area with the largest degree of genetic diversity at a general level by obtaining a value of 0. Altogether, the Agouti marker presented the largest genetic diversity value followed by the Extension plan, whose index was significantly higher than the domimance registered by the rest of the markers Table 4.

On average, the genetic variability what is population dominance on the total population was 0. With respect to the Hardy-Weinberg equilibrium test, at a general level the municipalities reported equilibrium. This also happened for all markers. Genetic differentiation and genic flow. The genetic differentiation level in Cienaga de Oro was very low 0. In contrast, the higher value of the genetic flow Also, the number obtained is higher than 1 and 4, which indicates that the populations behave like a metapopulation.

Population structure. The negative numbers in each marker and in average With values of It is important to highlight that the average F IS and F IT values do not move away too much from zero; therefore, it is assumed that the global population is close to the Hardy-Weinberg equilibrium. On the other hand, the average F ST value was low, which indicates the minor genetic differentiation that exists in other populations.

It is worth noting iw a similar value was recorded for what jobs can you do with a music production degree G ST coefficient. Genetic distance. In this context, San Antonio presented the dominnance genetic distance values in dominnance with the rest of the populations.

In relation to Pijiguayal and El Siglo, there is a considerable proximity, and also, they sominance a close relation with Los Mimbres. On the other hand, San Antonio was the farthest population from the other populations, but with an insignificant distance value, which allows to deduce that the populations altogether are very related. The elevated frequency of the Extension gene in all populations can be due to the hypothesis proposed by several authors 16which is based on the fact that the allele variations that make more melanin colors dark possible, are favored in the comparison with those colors with lighter tones.

Also, it has been demonstrated that the absorption capacity of calorie radiation is more frequent in animals with dark coat than in those animals with lighter coats This allows assuming that darker horses are better adapted to prevailing conditions in tropical climates, considering that equines are animals that usually spend the what is population dominance part of the day grazing.

On the other hand, the absence of white horses could be due to a particular condition that characterizes iw White marker, but in homozygosis it causes the death of the animal This fact explains the substantial reduction in the number of individuals that carry the gene. The presence of ;opulation majority of markers in El Siglo, shows a large variety of genes available in the area. This situation is possibly due to geographic proximity between the studied populations and the surrounding municipalities, which favored the movement of migrants from one population to another and therefore, a considerable genetic exchange.

This would explain the reduced number of genes reported eominance Los Mimbres, since this is the only population that does not have a direct contact with border populations. Therefore, to relate the adaptation and the coat color, as well as to highlight the importance of migration, are acceptable criteria in this research. Genetic diversity as well as its close relationship with the genetic flow level in populations also influences significantly in genetic distances Therefore, the distance values will be low as the diversity between populations is low.

This indicates a direct relationship between these variables, which indicates that the low genetic diversity levels found were determining on the distance values recorded. The whaat of heterozygotes obtained through different fixation indexes Dominace IS and F IT in each one of the populations, indicates that these present an almost homogeneous structure, which is a fact that would be attributable to the high what is population dominance flow among them since the existence of a high exchange of genes prevents endogamy events what is population dominance the populations 20 and provokes a reduction of homozygotes genotype.

Also, this would be related to the probable randomization of mating, a scenario expected in wwhat with Hardy-Weinberg equilibrium and that would facilitate the presence of null levels of consanguinity A crucial fact in populatiob of genetic distance is the size of the population since these two parameters have an indirect relation whatsapp video call not working iphone 12 which, as the population size decreases the higher the genetic distance with the rest of the populations In this context, it could be said that San Antonio, the population with the smallest size, resulted in the most distance population from a genetic point of view.

A possible response to the reduced number what is a negative control group in biology recorded individuals is due to the topographic characteristics of the area, since this municipality is located in between a mountain chain with a woody vegetation, conditions that would limit the keeping of horses and considering that these horses usually graze in plain areas without exuberant vegetation 1.

Dahlgren, J. Emerged seedlings were counted during April sampling, when emergence reaches its peak. This multispecies dynamic IPM was used to simulate stochastic population growth rates of both species under different climatic and ecological scenarios. Otherwise, the fact that was the only year in which the recruitment pulse was recorded, despite other years, such asoralso having similar spring rainfall amounts, suggests that not only spring rainfall, but its combination with other climatic drivers such as summer water balance which, actually, was the least negative in may be responsible for recruitment pulses.
