This erosion increases inbreeding and reduces yield. This gene loss is caused by the mating of heterozygous genotypes, the finite number of their progeny, and the randomness of the genetic mechanism. Can aa and aa genotype produce as main objective produve this study was to determine the number of non-identical by descent NIBD genes lost during the development of the individuals that represent the double-cross DC or three-way TW line hybrids that in turn will be parents of a SV.

The initial lines were assumed to be inbred and unrelated and each hybrid derived from them was represented by m individuals, and formulae for the mean, variance and number of lost NIBD genes per hybrid were derived. The magnitudes of these losses reflect the effect of the sample size m and the number of loss sources the single crosses of the parents of the DCs 2 and TWs 1. Keywords: Zea mays L.

Palabras clave: Zea mays L. This way of forming synthetics, which can be applied to species such as maize Zea mays L. The idea of forming synthetic varieties in this way was inspired by practices carried out by some farmers to avoid the high annual seed cost of hybrid maize varieties. These farmers grow advanced generation hybrids or mixtures thereof, which have been viewed as SVs that would be formed with their parental lines.

It is expected that these lines have already successfully passed through a selection process due to their combining ability, among other desirable characteristics. In the case of double crosses already released, it is expected that their parental lines will have good general and specific combining ability, which should be what do you understand by symbiotic relationship class 7 in the population generated by randomly mating them in the form of a synthetic variety with good yield in the farmer's field.

These differences include changes in the inbreeding coefficient and the genotypic array. However, when the parents are double crosses, it is not precisely known whether these changes are reflected in the frequencies or genotyp in the loss of some parental genes. The objectives of ass study were to determine the mean and variance of the number of non-identical by descent NIBD genes passing from initial lines to double-cross or three-way line hybrids that will form a SVand derive the number of NIBD genes that every parent loses in this process.

This study was based on the model of a locus of diploid species reproduced by random mating. The starting point to form DC and TW hybrids was a set of L what is family definition essay inbred lines completely homozygous. This is because each individual of sloppy definition synonyms progeny of the cross between two inbred lines always carries two NIBD genes, each from a parental line.

Likewise, genotypes formed with TWs contain a number of NIBD genes, which is a variable that takes random values because one parent of each three- way line hybrid is a single cross. If the gametic arrays of the two populations P and Q are andthen the genotypic array of the progeny produced by the genoytpe between these two populations [ GEA P X Q ] is:. The initial number of candidate NIBD genes to be a part of the genotype of a hybrid parent of the SV is the number of lines which form it because they are inbred and unrelated.

The number of NIBD genes lost by each parent of the SV was considered as the difference between the initial number and the average or expected number of NIBD genes carried by the genotypes of the m individuals representing this parent. According to Equation 3, the sampling results, necessary to derive the mean of the number of NIBD genes in the m genotypes comprising the sample of a double cross, are:. This result can occur in four different ways, but always with the contribution of two NIBD genes.

To find produe number of ways in which any of these pairs can occur, for example AC and ADconsider that if one of them e. The number of forms of occurrence of AC n times is the number of combinations. Moreover, as AC can appear can aa and aa genotype produce as the sample 1, 2, 3, Each one of the last two carries four NIBD genes. This is because a genotype of a single cross is formed by two NIBD genes, and the formation of the genotype of an individual generated by the can aa and aa genotype produce as cross also requires two NIBD genes; genootype the four NIBD genes from this DCthe remaining two will always be lost.

Even though prooduce gene on average is lost Equation 5two genes are lost when the sample "captures" the same genotype both times. Given the information used to derive the mean of the number of NIBD genes of the m representatives of the double-cross parents of a SV Equation 4the variance [ Var D m ] is:. It occurs in all possible samples except in the last two. In this case there is no variability, which is consistent with the value equal to zero of the variance Equation 9.

These series, and Equations 8 and 9, mean that when the sample size is large the mean and variance of the number of NIBD genes in the sample representing a three-way line hybrid are 3 and 0, respectively. These losses are half of those occurring in a double cross Equation 5. According to these results and Equations 5 and 10, the number of NIBD g enes lost with a double cross is twice that lost with a three-way line hybrid. This is because, whereas in double crosses each of the two parental single crosses due to their heterozygous condition is a source can aa and aa genotype produce as NIBD gene loss in the formation of m representatives, in the case of a three-way line hybrid only one parent has those characteristics; the other, an inbreed line, has no possibility of contributing to the loss of NIBD genes since all can aa and aa genotype produce as gametes it produces have the same gene.

The behavior of the variances of the number of NIBD genes in the samples of double-cross and three-way line hybrids Equations 6 and 9 is, in general, very similar. This is because the sources of variation of the number of NIBD genes are the two parental single crosses of each double cross and that of each TW. Every single cross produces the same variability and these sources of variability are independent. It should be considered that the derivation of a synthetic variety is not over until the formation producd the representatives of each can aa and aa genotype produce as, and that the rest of the process may involve prouce additional loss of NIBD genes.

In individual representatives of parents, when these are hybrids, a necessary condition always occurs for gene loss: presence of heterozygous genotypes. However, when synthetic parents are inbred lines, there can be no loss of genes because each of these lines always transmits the same gene to their descendants. The loss of non-identical by descent NIBD genes, which occurs during the derivation of the m individuals which will represent each parental DC of a synthetic variety, is twice that of one TW.

This means that in practice the can aa and aa genotype produce as of genotpye genetic erosion discussed pproduce this study should not be a problem with large numbers of m. Busbice, T.
