Using Labrador retrievers, you cross yellow females with yellow males repeatedly. In the resulting F2 progeny you would expect to see puppies that are a. 9 black:3 brown:4 yellow b. 1 black: 1brown: 14 yellow c. All black d. All yellow e. All brown 13) in populations in Hardy-Weinberg equilibrium, the heterorygote frequency is maximal when the A allele (p) equals a. b. 0.15 C. 0.25 d. 0.5 e. 0.8 14) If two populations of birds with frequencies of an allele a of 0.2 and 0.3 are forced together by unusually high winds, the new frequency of the a allele in the combined population will be a. 0.3 b. 0.2 c. 0.5 d. 0.25 e. 0.15 5) in an experimental population of fish, the genotype frequencies are 0.4BB, 0.4Bb, and 0.2bb. If all the BB fish are removed from the population, what will be the frequency of the B allele in the next generation? a. 10% b. 20% C. 33% d. 40% e. 62% In a human population, the genotype frequencies at one locus are 0.5AA, 0.4 Aa, and 0.1 aa. The frequency of the A allele is a. 0.32 b. 0.75 c. 0.2 d. 0.7 e. 0.9
