Four different populations of an owl species were studied. Data were collected on population sizes and the frequencies of alleles for one gene. The gene is not known to be under any selective pressures. If genetic drift is the only mechanism operating to change these allele frequencies over time, which population can be expected to show the greatest change and which can be expected to show the least change over time?

1 - size 58, A=.75, a=.25

2 - size 289, A=.95, a=.05

3 - size 592, A=.80, a=.20

4 - size 160, A=.88, a=.12

A) Greatest change = 3; least change = 4

B) Greatest change = 4; least change = 2

C) Greatest change = 2; least change = 1

D) Greatest change = 1; least change = 3
