Column A
1. natural selection
2. hardy-weinberg law
3. genetic drift
4. gene flow
5. mutation

Column B
A. this genetic change can occur in any population of non-infinite size, but it has a stronger effect on small populations.
B. it is the reason behind genetic variation.
C. this states that in an infinitely large, interbreeding population in which mating is random in which there is no selection, migration, or mutation, gene and genotype frequencies will remain constant from generation to generation.
D. this occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment.
E. it is used to calculate the genetic variation of a population at equilibrium.
F. this involves the movement of genes into or out of a population, due to either the movement of individual organism of their gametes (eggs and sperm, e.g., through pollen diperal by a plant ).​
