WebJun 18, 2024 · Traditionally, the degree of inbreeding depression in livestock has been estimated as the slope of the linear regression of phenotypic values on pedigree-based inbreeding coefficients. With the increasing availability of SNP-data, pedigree inbreeding can now be replaced by SNP-based measures.

WebInbreeding Depression in Small Populations. Inbreeding is unavoidable in small, closed populations because all individuals eventually become related to each other. Inbreeding in an effective population of size (N e) increases at a rate of 1/(2N e), per generation with random mating. For example, in an effective population of size 10, there is a ...
