Question

What does the Hardy-Weinberg equation \[p^2 + 2pq + q^2 = 1\] represent?

Options

• Allele frequencies across multiple generations

• The probability of random mating events

• Genotype frequencies in a population at equilibrium

• The rate of mutation in a population

Answer 1

The Hardy-Weinberg equation \[p^2 + 2pq + q^2 = 1\] is the binomial expansion of \[(p + q)^2\] and represents genotype frequencies at equilibrium, where \[p^2\] represents homozygous dominant (AA), \[2pq\] represents heterozygous (Aa), and \[q^2\] represents homozygous recessive (aa) frequencies.
