In the context of Hardy-Weinberg equilibrium, which of the following best defines a gene pool?

In a population at Hardy-Weinberg equilibrium with an allele frequency of q = 0.25 for a recessive allele, what is the expected frequency of heterozygotes?

Which of the following statements is NOT a part of the Hardy–Weinberg principle?

If the Hardy-Weinberg equilibrium is met in a population, what is the net effect?

In a population at Hardy-Weinberg equilibrium, if the frequency of the g allele is 0.6, what percentage of all alleles in the population are g?

In the context of Hardy-Weinberg equilibrium, what is a gene pool?

In the context of Hardy-Weinberg equilibrium, what does allele frequency refer to in a population?

Under ideal Hardy-Weinberg conditions (very large population, random mating, no mutation, no migration, and no natural selection), how do allele frequencies change over time?

Under Hardy-Weinberg assumptions, a diploid population has genotype frequencies $f_{AA}$, $f_{Aa}$, and $f_{aa}$. Which expression correctly calculates the allele frequency of $A$ (i.e., $p$) from these genotype frequencies?
