Use the photo of the betta fish to answer Question 3.
3. A gene mutation in the beta fish results in a
double-tail. In this example, the mutation
results in a change to a physical trait
/ behavior. This change is desirable
by fish breeders but does not provide a
survival advantage for the fish, so it is lis
not considered an adaptation.

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
