Humans have hair color that ranges from black, brown, and red to blonde. This is an example of a A. gene transfer. B. polymorphism. C. chromosomal variation. D. monomorphic gene. 3. In a population of mice, 36 are black with the genotype BB, 48 are gray with the genotype Bb, and 16 are white with the genotype bb. What is the frequency of b? A. 0.64 or 64% B. 0.6 or 60% C. 0.4 or 40% D. 0.16 or 16% 4. In a population of mice, 36 are black with the genotype BB, 48 are gray with the genotype Bb, and 16 are white with the genotype bb. What is the frequency of B? A. 0.84 or 84% B. 0.6 or 60% C. 0.4 or 40% D. 0.36 or 36% 5. In the Hardy-Weinberg equation, p + q = A. 0. B. 0.1. C. 1. D. 10. 6. In the Hardy-Weinberg equation, the letters p and q represent A. frequencies of alleles in a population. B. the number of individuals of different phenotypes in a population. C. the number of individuals of different genotypes in a population. D. the frequencies of individuals of different genotypes in a population. 7. If a population is in Hardy-Weinberg equilibrium, this means that A. the frequency of alleles in the population is not changing. B. the population is not adapting and evolution is not occurring. C. the population will change in size in the near future. D. the frequency of alleles in the population is not changing and the population is not adapting and evolution is not occurring are correct. 8.
