Calcolatore della frequenza genotipica

Frequenze genotipiche di Hardy-Weinberg a partire dalla frequenza allelica p.

Introduzione

Genotype Frequency Calculator — Hardy-Weinberg genotype frequencies from allele frequency p. Enter Dominant allele frequency (p) to get an instant, accurate result.

Formula

Hardy-Weinberg genotype frequencies from the dominant allele frequency p (with q = 1 − p): AA = p², Aa = 2pq, aa = q². These three frequencies always sum to 1.

Passo dopo passo

  1. Enter the Dominant allele frequency (p).
  2. Click Calculate to see your result instantly.

Esempio pratico

Example: With Dominant allele frequency (p) = 0.7, the Genotype Frequency Calculator gives A A: 0.49, Aa: 0.42, Aa: 0.09.

Domande Frequenti

What assumptions does Hardy-Weinberg require?
It assumes a large population, random mating, no mutation, no migration, and no natural selection — real populations only approximate these conditions.
Why is the heterozygote frequency 2pq and not pq?
A heterozygote can arise two ways — a dominant allele from one parent with a recessive from the other, or vice versa — so the pq probability is counted twice.
What inputs does the Genotype Frequency Calculator need?
You'll need to provide: Dominant allele frequency (p). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Genotype Frequency Calculator?
The Genotype Frequency Calculator applies the formula exactly as calculated — Hardy-Weinberg genotype frequencies from the dominant allele frequency p (with q = 1 − p): AA = p², Aa = 2pq, aa = q². These three frequencies always sum to 1. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Genotype Frequency Calculator free to use?
Yes, the Genotype Frequency Calculator is completely free, requires no signup, and runs instantly in your browser.

The Genotype Frequency Calculator uses a real, verifiable formula — Hardy-Weinberg genotype frequencies from the dominant allele frequency p (with q = 1 − p): AA = p², Aa = 2pq, aa = q². These three frequencies always sum to 1. — so results are accurate every time, not an approximation.
