Without genetic variation, the mechanisms of evolutionary change will not occur. There are several sources of genetic variation within a breeding population: sexual reproduction, mutation, and gene flow. Specifically, sexual reproduction contributes to genetic variation and as a result, evolution, through recombination. Describe the recombination and analyze how it contributes to genetic variability. Choose ALL that apply. I have the answers to this, but I had to ask it to answer it.
