There are three isolated populations of garter snakes: population A has had a constant population size of about 50,000, population B has had a constant population size of about 12,000, and population C has had a constant population size of about 2,000.We would expect to see the greatest fluctuations of allele frequencies in population _______ because this population would experience the _______ genetic drift.
A) A; most
B) A; least
C) B; most
D) C; most
E) C; least
