What is one factor that affects natural selection and artificial selection?
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
