Question

Suppose you are involved in a project studying a population of Dalea purpurea (purple prairie clover), a diploid, bee pollinated plant growing at Cayler Prairie in NW Iowa. You collect a sample from 100 individuals and assay DNA sequence variation at the apetala locus, which controls floral morphology. You find two distinct sequences: L and S. Individuals that are LL have very large petals, LS plants have medium sized petals, and SS plants have small petals. Your sample of plants yields the following observed and Hardy-Weinberg expected (HWE) genotypic counts:.Genotype: Observed Counts: HWE Counts:LL 14 9LS 32 42SS 54 49a. The population is in Hardy-Weinberg equilibrium, giving no indication of the preferences of the bees.b. LS heterozygotes are favored due to hybrid vigor.c. Bees are preferentially visiting smaller flowers resulting in a reproductive advantage for plants with smaller petals.d. LL genotype plants have a reproductive advantage due to their larger flowers.e. Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.

Answer 1

Answer:

Option E

Explanation:

Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.

Inbreeding increases the frequency of homozygousity and deviates from the assumptions of the hardy Weinberg's principle
