Hardy-Weinberg Equilibrium

Definition

A model in which allele and genotype frequencies stay constant in a non-evolving population.

1 / 7
Hardy-Weinberg Equilibrium
Not Started

A model in which allele and genotype frequencies stay constant in a non-evolving population.

7.5.A7.5.A.1
Null Hypothesis for Evolution
Not Started

The expectation that allele frequencies remain unchanged unless evolutionary forces act on the population.

7.5.A7.5.A.1
Hardy-Weinberg Equations
Not Started

p + q = 1 for allele frequencies; p^2 + 2pq + q^2 = 1 for genotype frequencies.

7.5.A7.5.A.2
p and q
Not Started

p is the frequency of one allele; q is the frequency of the other allele.

7.5.A7.5.A.2
p^2, 2pq, and q^2
Not Started

p^2 is homozygous dominant, 2pq is heterozygous, and q^2 is homozygous recessive.

7.5.A7.5.A.2
Calculating Allele Frequencies From Genotype Frequencies
Not Started

Find q from q^2 if needed, calculate p as 1 minus q, then use p^2, 2pq, and q^2.

7.5.A7.5.A.2
Hardy-Weinberg Conditions
Not Started

Large population, no migration, no mutation, random mating, and no natural selection prevent allele frequency change.
