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. 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?

Two large populations of horses are being systematically crossed (mares from one population bred to stallions of the other and vice versa). Coat color is NOT a factor in determining which animals are selected and which individual matings are made. Frequencies of coat color genes at the C locus are: Population 1: C = 0.8, ccr = 0.2 Population 2: C = 0.3, ccr = 0.7 What will be the frequency of Q at the C locus in the offspring (F1) population?
