Hardy Weinberg Calculator: Master Population Genetics

The hardy weinberg calculator is the gold standard for population genetics. This hardy weinberg calculator computes allele and genotype frequencies, heterozygosity, and tests for equilibrium.

"P² + 2pq + q² = 1" — Hardy-Weinberg Principle

How the Hardy Weinberg Calculator Works

Our hardy weinberg calculator uses:

  • p²: AA frequency
  • 2pq: Aa frequency
  • q²: aa frequency
  • p + q = 1
  • Chi-square test (df=1)

Hardy Weinberg Calculator: Key Outputs

  • p: Frequency of dominant allele
  • q: Frequency of recessive allele
  • H: Heterozygosity (2pq)
  • FIS: Inbreeding coefficient
  • Chi-square p-value

Why Use This Hardy Weinberg Calculator?

Trusted globally:

  • Real-Time Results
  • Chi-Square Test
  • HWE Violations
  • Export Data
  • Mobile-Optimized

Hardy Weinberg Calculator: Assumptions

Population must have:

  • No mutation
  • No migration
  • No selection
  • Random mating
  • Infinite population size

Hardy Weinberg Calculator Limitations

This hardy weinberg calculator assumes diploid organisms and two alleles. Real populations often deviate due to drift, selection, or non-random mating.
