Document Summary
Most of the day tuesdays and thursdays. Multiple choice scantron: lactase intolerance cont. Lactase persistence continue to produce lactase enzymes and can therefore digest dairy prodcuts: frequencies of lactose intolerence.

A gene pool is the total complement of genes shared by the reproductive members of a population. Breeding isolates are populations that are isolated geographically and or social from the other breeding groups.
