If a population experiences no migration, is very large, has no mutations, has random mating, and there is no selection, which of the following would you predict?

• The population will evolve, but much more slowly than normal

• The makeup of the population's gene pool will remain virtually the same as long as these conditions hold.

• The composition of the population's gene pool will change slowly in a predictable manner.

• Dominant alleles in the population's gene pool will slowly increase in frequency while recessive alleles will decrease.

• The population probably has an equal frequency of A and a alleles.

If the frequency of two alleles in a gene pool is 90% A and 10% a, what is the frequency of individuals in the population with the genotype Aa?

• 0.81

• o.09

• 0.18

• 1.01

Which of the following is NOT a condition that must be met for Hardy-Weinberg equilibrium?

• Large population size

• No mutations

• No immigration or emigration

• Dominant alleles are more frequent than recessive alleles

• No natural selection

In a population that is in Hardy-Weinberg equilibrium, the frequency of the homozygous recessive genotype is 0.09. What is the frequency of individuals that are homozygous for the dominant allele?

• 0.7

• o.21

• 0.42

• 0.49

• 0.91

In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh-positive phenotype is produced by a dominant gene (A), and the Rh-negative phenotype is due to its recessive allele (a), what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive?

• 0.04

• 0.16

• 0.48

• 0.60

• 0.84
