For example, the allele in the Acyl-CoA:diacylglycerol acyltransferase 1 (DGAT1) increases milk fat content and decreases milk yield in dairy cattle [27], and the risk allele FYVE, RhoGEF and PH domain-containing protein 3 (FGD3) of skeletal dysplasia increases carcass weight [28]. Here, FGD3 is linked to skeletal dysplasia.
