For questions #16-19 use the scenario below to help answer. A biologist spent many years researching the rate of evolutionary change in the finch populations of a group of islands. It was determined that the average beak size (both length and mass) of finches in a certain population increased dramatically during an intense drought between 1981 and 1987. During the drought, there was a reduction in the number of plants producing thin-walled seeds.

In fruit flies (Drosophila melanogaster), straight wing shape is dominant to curly wing shape. A particular population of fruit flies is in Hardy-Weinberg equilibrium with respect to the alleles for wing shape. The Hardy-Weinberg equation, given below, is useful in understanding population genetics: p2 + 2pq + q2 = 1
