Beta-casein in milk is mainly in two types A1 and A2, of which A2 milk contains only the same type.

In principle, all cows carried the A2 beta-casein gene exclusively, but over time they underwent a genetic mutation that led to a different version of the beta-casein gene. Modern migration and farming are among the causes of this genetic mutation; Which eventually created a population of different cows that could produce A2, A1, or both types of beta-casein.
