Hardy-Weinberg Equilibrium Review

Flashcards on Hardy-Weinberg Equilibrium

Hardy-Weinberg Equilibrium

When a population's gene pool does not evolve and allele frequencies remain constant across generations.

Hardy-Weinberg Assumptions

No mutations, random mating, no gene flow, large population size, and no selection.

p

Represents the frequency of the dominant allele.

q

Represents the frequency of the recessive allele.

Hardy-Weinberg Equation

p + q = 1

p2+2pq+q2=1

The equation used to calculate the expected genotype frequencies in a population that is in Hardy-Weinberg equilibrium, where p2 represents the frequency of homozygous dominant individuals, 2pq represents the frequency of heterozygous individuals, and q2 represents the frequency of homozygous recessive individuals.

p2

homozygous dominant

2pq

Heterozygous individuals

q2

reccessive individuals in the population
