1. Explain how recombination facilitates adaptive evolution. In your answer, address both how it facilitates the fixation of adaptive alleles, and how it allows continued long term adaptive change. What evidence suggests that species that never do recombination tend to go extinct at a higher rate than those that do recombination at least occasionally.

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
