Selective Breeding And Heritability Animal Reproduction And Breeding Variation in breeding values is equivalent to additive genetic variation, which can be divided by phenotypic variation to give heritability. In this study, we propose an extension of the concept for heritability on an entry mean to an entry difference basis, which allows for more detailed insight and is more meaningful in the context of selection in plant breeding, because the correlation among entry means can be accounted for.
Chapter 6 Quantitative Traits Breeding Value And Heritability Heritability expresses the proportion of the total phenotypic variance that is attributable to the average effects of genes, which in turn determines the degree of resemblance between the. Figure 2.1 the relationship between breeding value and phenotype, depending on heritability. the higher the heritability, the larger the part of phenotypic difference that is attributed to breeding value. Heritability is often used by plant breeders and geneticists as a measure of precision of a trial or a series of trials. its main use is for computing the response to selection. most formulas proposed for calculating heritability implicitly assume balanced data and independent genotypic effects. According to falconer and mackay (1996) [10], heritability is defined as the measure of the correspondence between breeding values and phenotypic values. thus, heritability plays a predictive role in breeding, expressing the reliability of phenotype as a guide to its breeding value.

Only the phenotypic value of the individual can be directly measured, but it is the breeding value that determines their influence on the next generation. The study aims to estimate the heritability and breeding value of weaning weight of garut sheep at uptd bpptdk margawati garut. the research objects used were 89 data from 25 males and 75 femaes. Heritability describes how much of the differences in phenotypes among animals treated similarly is due to genetics. it is the most basic connection from phenotype to dna and genetic evaluation. heritability is the ratio of genetic variance (vg) to phenotypic variance (vp) and ranges from 0 to 1. Ultimately, i find that there are two main uses for heritability in plant breeding: the first is to predict the response to selection and the second is as a descriptive measure for the.
