Question

Evidence for natural selection favoring the lactase persistence trait comes from:

Long stretches of homozygosity around the lactase gene in lactase persistent people but not in people with the non-persistent trait.

Strong purifying selection eliminating most variation around the lactase gene in populations where cattle domestication originated.

High levels of sequence diversity in genomic regions surrounding the lactase gene.

Higher rates of survival and reproduction in populations that raise cattle.
