Question

Heavy flooding kills all of the striped ground squirrels in a population, leaving only solid-colored squirrels that lack an allele for stripes. Which term best describes the loss of the striped allele from the ground squirrel population?

a. founder effect
b. gene migration
c. genetic drift
d. gene flow

Answer 1

i think the answer is d, gene flow

Answer 2

The best description which tells us what happened to the poor squirrels and relates to what happens when you have a certain specific species which get died out would be gene flow.

The gene flow of the striped ground squirrels was wiped out essentially, leaving onl the solid-color squirrel gene pool :)
