Q4.9. The allele for black noses in wolves is dominant over the allele for brown noses. There is no known selective advantage for one nose color over another in wolves. If this remains true, which of the following statements is most likely TRUE about the change in wolf nose colors over many generations? Black noses will become more common than they are now. Black noses will stay about the same frequency as now. Black noses will become less common than they are now. Brown noses will disappear after enough generations pass. Q4.10. A large population of land turtles on an isolated island has two alleles for a gene that determines shell thickness. The allele for thinner shells is dominant over the allele for thicker shells. The thinner-shell allele occurs at a frequency of 20%. Assuming there is no net advantage to thick or thin shells, what should the frequency of homozygous thicker-shelled turtles be in the population? (Hint: Use a population Punnett square to calculate the answer.) 4% Sutimit 16% 50% 1/1 15 RO 64% s.doc
