population - ANSWER an interbreeding (sharing genetic information) group of individuals who live in the same geographic area and exist at the same time variability within a species/population (importance) - ANSWER important because: -some genetic variations have advantages over others -natural selection can act on the variation that arises What if populations are separated and can't exchange genes? - ANSWER two processes can occur: 1. genetic divergence 2. speciation genetic diverg...
