What is a breeding value?
What is a breeding value based on EBV?
Why is estimated breeding value more accurate than mass selection?
Are individual traits a breeding value?
Selection on genetic merit using estimated breeding values is more accurate, particularly for lowly heritable or sex-limited traits, and enables faster genetic gain than mass selection using phenotypes. The estimated breeding value encompasses not just the phenotypic information of the individual, but also information from relatives.
The additive genetic value of an individual, called the breeding value, is the sum of the average effects of all the alleles the individual carries (Falconer &...
Apr 15, 2020 · In plant breeding, the main focus of quantitative genetics is on identifying candidates with the best genotypic value for a target population of environments.

breeding value is the phenotype. For this purpose we use phenotypic differences between animals, or more specifically, phenotypic deviations. The breeding value is now estimated as a proportion of this deviation, being the proportion of total variation that is due to variation in breeding value.

Breeding values are average effects of genes that are transmitted by a parent to an offspring. Genetic change due to selection based on EBV will be lower than if selection had been on true breeding value. The relative response is proportional to accuracy of EBV, and accuracy is between 0 and 1.
Sep 10, 2017 · Breeding value (BV) is the value of an individual measured by the mean phenotype of its progeny obtained by random mating with the population (Falconer and Mackay 1996). Breeding value measures the average effect of an individual’s alleles as they affect progeny performance, rather than the performance of the individual itself (which is its ...
Jan 19, 2022 · In animal and plant breeding, we often need to estimate the “breeding value” of an individual for a quantitative trait of interest. We first define the breeding value as the heritable part of the difference between the individual’s phenotypic value and the mean phenotypic value of the population.
