Production traits in farm animals are mostly quantitative traits. They have continuously distributed phenotypes that do not show simple Mendelian inheritance. These traits are controlled by a large ...

Epistasis arises when alleles at one locus modify the phenotypic expression of alleles at another, generating non-additive contributions to trait variation. In natural populations, genetic variance ...

Sequencing nearly half a million genomes, researchers show that most additive genetic influences on height, lipids, and other complex traits are now directly measurable, while pinpointing ultra-rare ...
