The goldenrod gall-fly lays its eggs on the terminal buds of goldenrod plants. larvae chew through the buds and into the stems, where their saliva induces the plant to generate a gall, or outgrowth of tissue, that then provides food and shelter for the developing larva. the larvae are prey to both parasitoid wasps and to birds; wasps selectively prey on larvae inside the smallest galls while birds selectively prey on larvae inside the largest galls. goldenrod gall-flies are therefore subject to what selection?

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
