Background: Cow's milk β-casein has multiple genetic variants, the two most common of which are A1 and A2, which are encoded by the CSN2 gene. Evidence suggests that the A1 variant may negatively affect human health. Type A2 milk is a safer alternative for human consumption because it is easier to digest than A1. Aim: To determine the frequency of the A1 and A2 alleles of the β-casein gene in cattle. Methods:...
