Two approaches to account for genotype-by-environment interactions for production traits and age at first calving in South African Holstein cattle
If not accounted for, genotype x environment (G ×E) interactions can decrease the accuracy of genetic evaluations and the efficiency of breeding schemes. These interactions are reflected by genetic correlations... (Source: Genetics Selection Evolution)

Rare and population-specific functional variation across pig lines
It is expected that functional, mainly missense and loss-of-function (LOF), and regulatory variants are responsible for most phenotypic differences between breeds and genetic lines of livestock species that ha... (Source: Genetics Selection Evolution)

Single-step genomic BLUP with genetic groups and automatic adjustment for allele coding
Genomic estimated breeding values (GEBV) by single-step genomic BLUP (ssGBLUP) are affected by the centering of marker information used. The use of a fixed effect called J factor will lead to GEBV that are una... (Source: Genetics Selection Evolution)

Genetic variants associated with two major bovine milk fatty acids offer opportunities to breed for altered milk fat composition
Although bovine milk is regarded as healthy and nutritious, its high content of saturated fatty acids (FA) may be harmful to cardiovascular health. Palmitic acid (C16:0) is the predominant saturated FA in milk... (Source: Genetics Selection Evolution)

Recombination rates in pigs differ between breeds, sexes and individuals, and are associated with the RNF212, SYCP2, PRDM7, MEI1 and MSH4 loci
Recombination is a fundamental part of mammalian meiosis that leads to the exchange of large segments of DNA between homologous chromosomes and is therefore an important driver of genetic diversity in populati... (Source: Genetics Selection Evolution)
