Apopulation 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?
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
an increase in mutations in the island population

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
