Does race have much to do with lactose tolerance? I know that some cultures are largely lactose-intolerant (much of Asia, for example), but I believe that has more to do with cultural dietary choices than genetics, as all humans are technically lactose-intolerant after infancy.

Some populations have evolved permanent lactase production after infancy.
Lactase persistence does not require you to continue drinking milk after childhood. If you have it, you have it.
Also it’s not just some cultures, most of the world is lactose intolerant.
