Chapter 23 – Additional Hardy-Weinberg Equilibrium Problems 1. If 9% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be more resistant to malaria because they are heterozygous (Ss) for the sickle-cell gene? 2. This is a classic data set on wing coloration in the scarlet tiger moth (Panaxia dominula). Coloration in this species had been previously shown to behave as a single-locus, two- allele system with incomplete dominance. Data for 1612 individuals are given below: White-spotted (AA) =1469; Intermediate (Aa) = 138; Little spotting (aa) =5 Calculate the following frequencies: A, a, AA, Aa, aa

Unformatted text preview: 3. After graduation, you and 19 friends build a raft, sail to a deserted island, and start a new population, totally isolated from the world. Two of your friends carry (that is, are heterozygous for) the recessive cf allele, which in homozygotes causes cystic fibrosis. a) Assuming that the frequency of this allele does not change as the population grows, what will be the instance of cystic fibrosis on your island? b) Cystic fibrosis births on the island are how many times greater than the original mainland. The frequency of births on the mainland is .059%....
