Population - ANSWER A group of individuals that belong to the same species and live in the same area Purpose of variability within a population - ANSWER - some genetic variants have advantages over others - natural selection can act on variation (if needed) genetic divergence - ANSWER the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often after the populations have become reproductively isolated for some ...

What is a population? - ANSWER interbreeding of a group of individuals who have the same species, geographics and time period.
