By studying a large population of sego lilies (Calochortus nuttallii) on the side of Kinport Peak, your colleague is interested in knowing the degree to which global climate change is affecting natural populations in Idaho. Her hypothesis is that a rare drought tolerant variant (genotype dd) might be increasing in frequency over heterozygotes (Dd) or homozygotes for the wild type allele (DD). You use molecular techniques to genotype a sampling of sego lilies, finding 130 DD, 50 Dd, and 10 dd. Test for HW equilibrium and draw conclusions about evolutionary forces acting on the population.
