The colors of individuals in a snail population are determined by a single autosomal locus. A1A1 homozygotes are red, A1A2 heterozygotes are pink, and A2A2 homozygotes are white. Genotypic fitnesses are as follows: wA1A1 = 0.5; wA1A2 = 1.0; wA2A2 = 0.75. At equilibrium,

Long term exposure to waves can cause sunburns and skin cancer.

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
