The next generation will also have the same frequencies. Also list some proximate sources of genetic variation.
Mutation is the ultimate source of all variation.
New combinations of old genes can also occur through recombination, segregation, and sex. List all possible mechanisms discussed in class. Mutation, recombination, sex, segregation, some types of selection, and migration. Discuss each pair-wise case. Genetic drift can erode allelic variation in a population by random sampling error of the alleles that will contribute to the next generation.
