Question

question 3 of 19
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.
□ one phenotype has a higher survival rate.
□ there is no net mutation of genes.
□ the population size is unimportant.
□ random mating occurs within the population.
□ there is no migration in or out of the population.
□ the population has two alleles of a gene, and one allele is dominant.

Explanation:

The Hardy-Weinberg equilibrium assumptions include no net mutation, random mating, no migration, infinite population size (so population size is important), no natural selection (so no phenotype has higher survival rate), and the number/dominance of alleles are not required assumptions (the principle applies to any number of alleles). Thus the correct statements are the three listed.

Answer:

There is no net mutation of genes., Random mating occurs within the population., There is no migration in or out of the population.
