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.

The lineage of pea plants produced round seeds for four generations. the plants that fertilized these pea plants also produced round seeds. however, in the fifth generation, the plant produced to two plants with wrinkled seeds. can that be possible?

Assume that you are interested in separating short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range. you have two recipes for making your polyacrylamide gels: one recipe uses 1.5 percent agarose and would be considered a βhard gel,β while the other uses 0.5 percent agarose and would be considered a loose gel. which gel should you use to separate the short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range?
