What is the role of variation in evolution – if heterozygosity is reduced, what happens to the potential for evolution?
Generally, will natural selection result in an increase or decrease in variation? Why does this happen, and how, in theory, will it affect evolution in the future?
What is the role of genetic variation in natural selection?
