Hardy-Weinberg Calculator

Calculate allele frequencies, genotype frequencies, and test for Hardy-Weinberg equilibrium in populations.

Input Data

Input Mode

Dominant Allele Frequency (p)

Population Size

Hardy-Weinberg Equation

p² + 2pq + q² = 1

p + q = 1 (allele frequencies sum to 1)

Allele Frequencies

p (dominant)

0.6000

q (recessive)

0.4000

Genotype Frequencies

AA (p²)0.3600 (36.00%)

Expected: 360 individuals

Aa (2pq)0.4800 (48.00%)

Expected: 480 individuals

aa (q²)0.1600 (16.00%)

Expected: 160 individuals

Assumptions

• No natural selection
• No genetic drift (large population)
• No gene flow (migration)
• No mutation
• Random mating
