A population of organisms is said to be in Hardy-Weinberg equilibrium if it is not evolving. In a population that is not evolving, the frequency of alleles, genotypes, and phenotypes remains stable over generations. There are several assumptions that must be true for a population to be in Hardy-Weinberg equilibrium. Select all of the statements that are assumptions of a population in Hardy-Weinberg equilibrium.

a. The population has two alleles of a gene, and one allele is dominant.

b. There is no net mutation of genes.

c. One phenotype has a higher survival rate.

d. Random mating occurs within the population.

e. Migration does not occur to or from the population.

f. The population size is unimportant.

b. There is no net mutation of genes.

d. Random mating occurs within the population.

e. Migration does not occur to or from the population.

Explanation:

Assumptions of a population in Hardy-Weinberg equilibrium are:

1. No mutation

2. Random mating

3. No natural selection

4. Extremely large population size

5. No gene flow (migration)
