Bias in genomic predictions by mating practices for linear type traits in a large-scale genomic evaluation.

Journal of dairy science - 1 Jan 2021

Tsuruta S, Lawlor T J, Lourenco D A L, Misztal I

Abstract excerpt

The objective of this study was to clarify how bias in genomic predictions is created by investigating a relationship among selection intensity, a change in heritability (Δh2), and assortative mating (ASM). A change in heritability, resulting from selection, reflects the impact that the Bulmer effect has on the reduction in between-family variation, whereas assortative mating impacts the within-family variance or...
