Fenotip Frekansı Hesaplayıcı

Hardy-Weinberg altında dominant ve resesif fenotip frekansı.

Giriş

Phenotype Frequency Calculator — Dominant vs recessive phenotype frequency under Hardy-Weinberg. Enter Dominant allele frequency (p) to get an instant, accurate result.

Formül

Given allele frequency p under Hardy-Weinberg equilibrium (q = 1 − p): dominant phenotype frequency = p² + 2pq (AA plus Aa genotypes), recessive phenotype frequency = q² (aa only, since recessive alleles are only expressed when homozygous).

Adım adım

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

Gerçek dünya örneği

Example: With Dominant allele frequency (p) = 0.7, the Phenotype Frequency Calculator gives Dominant Phenotype: 0.91, Recessive Phenotype: 0.09.

Sıkça Sorulan Sorular

Why does the dominant phenotype combine two genotypes?
Both the homozygous dominant (AA) and heterozygous (Aa) genotypes display the dominant phenotype when the dominant allele is fully dominant, so their frequencies are added together.
Can I determine genotype frequencies from phenotype frequencies alone?
Only partially — the recessive phenotype frequency (q²) lets you solve for q and then p, but AA and Aa individually can't be distinguished by phenotype alone; you'd need genotype frequency results for that split.
What inputs does the Phenotype 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 Phenotype Frequency Calculator?
The Phenotype Frequency Calculator applies the formula exactly as calculated — Given allele frequency p under Hardy-Weinberg equilibrium (q = 1 − p): dominant phenotype frequency = p² + 2pq (AA plus Aa genotypes), recessive phenotype frequency = q² (aa only, since recessive alleles are only expressed when homozygous). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Phenotype Frequency Calculator free to use?
Yes, the Phenotype Frequency Calculator is completely free, requires no signup, and runs instantly in your browser.

Fenotip Frekansı Hesaplayıcı Hakkında

The Phenotype Frequency Calculator uses a real, verifiable formula — Given allele frequency p under Hardy-Weinberg equilibrium (q = 1 − p): dominant phenotype frequency = p² + 2pq (AA plus Aa genotypes), recessive phenotype frequency = q² (aa only, since recessive alleles are only expressed when homozygous). — so results are accurate every time, not an approximation.
