Abstract excerpt
BACKGROUND: Caseins are the major proteins found in cow's milk. There are four known casein fractions: αS1-casein, αS2-casein, β-casein and κ-casein, encoded by the CSN1S1, CSN1S2, CSN2 and CSN3 genes located on the sixth chromosome of cattle. These genes are considered candidate genes in marker-assisted selection. Therefore, it is essential to determine the relationship between these genes and quantitative...
