Which statement best describes Hardy-Weinberg equilibrium and what p and q represent?

Which statement best describes Hardy-Weinberg equilibrium and what p and q represent?

• A. No mutation, random mating, no migration, very large population, no selection; p is the frequency of the dominant allele and q is the frequency of the recessive allele; p + q = 1.
• B. It assumes mutation occurs in every generation and migration is mandatory; p and q are mutation rates; p+q=2.
• C. It requires small population size and selection; p and q are genotype frequencies.
• D. It assumes recessive alleles cannot exist; p and q sum to 0.5.

Answer: (A)
