Researchers studying a small milkweed plant population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. In this population, the genotypic frequencies are TT= 56, Tt = 28, and tt = 16. For each problem below, show all of your work. A. Calculate the observed allele frequencies. B. Calculate the expected genotypic frequencies. C. Is this population in HW equilibrium? If not, explain what may cause it to not be (for example, is one level of toxin more adaptive than others?).
