A population of birds lives on a small island. Another population of the same species lives on the mainland. The
distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars
and tiny islands have formed between the island and the mainland.
What is the most likely effect of this?
O an increase in mutations in both bird populations
an increase in gene flow between the bird populations
an increase in genetic drift between the bird populations
O an increase in mutations in the island population
