Kalkulator szachownicy Punnetta

Klasyczne krzyżowanie w szachownicy Punnetta dla jednego genu.

Wprowadzenie

Punnett Square Calculator — Classic Punnett square cross for a single gene. Enter Parent 1 genotype, Parent 2 genotype to get an instant, accurate result.

Wzór

Builds a 2×2 monohybrid Punnett square by pairing each of parent 1's two alleles with each of parent 2's two alleles (4 combinations total), producing the offspring genotypes and their ratios — e.g. Aa × Aa gives 1 AA : 2 Aa : 1 aa.

Krok po kroku

  1. Enter the Parent 1 genotype.
  2. Enter the Parent 2 genotype.
  3. Click Calculate to see your result instantly.

Przykład z życia

Example: With Parent 1 genotype = Aa, Parent 2 genotype = Aa, the Punnett Square Calculator gives Genotypes: AA, Aa, Aa, aa, Ratios: 1, 2, 1.

Często Zadawane Pytania

How is dominance shown in the offspring genotype?
The dominant (uppercase) allele is conventionally listed first in each offspring genotype, e.g. "Aa" rather than "aA", though both represent the same heterozygous genotype.
What does the classic 3:1 ratio mean?
Crossing two heterozygotes (Aa × Aa) produces genotypes in a 1 AA : 2 Aa : 1 aa ratio, which translates to a 3:1 dominant-to-recessive phenotype ratio if A is fully dominant.
What inputs does the Punnett Square Calculator need?
You'll need to provide: Parent 1 genotype, Parent 2 genotype. 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 Punnett Square Calculator?
The Punnett Square Calculator applies the formula exactly as calculated — Builds a 2×2 monohybrid Punnett square by pairing each of parent 1's two alleles with each of parent 2's two alleles (4 combinations total), producing the offspring genotypes and their ratios — e.g. Aa × Aa gives 1 AA : 2 Aa : 1 aa. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Punnett Square Calculator free to use?
Yes, the Punnett Square Calculator is completely free, requires no signup, and runs instantly in your browser.

O Kalkulator szachownicy Punnetta

The Punnett Square Calculator uses a real, verifiable formula — Builds a 2×2 monohybrid Punnett square by pairing each of parent 1's two alleles with each of parent 2's two alleles (4 combinations total), producing the offspring genotypes and their ratios — e.g. Aa × Aa gives 1 AA : 2 Aa : 1 aa. — so results are accurate every time, not an approximation.
