🧬 Scientific Mendelian Genetics

Bird Genetics Calculator

Select visual mutations and hidden carrier splits for each parent. Calculate expected offspring colors, sex distribution, and split ratios using Mendelian Punnett squares.

♂ Sire (Male)

* Avian rule: Females carry ZW chromosomes and cannot be split for sex-linked traits (Ino, Cinnamon, etc.).

Frequently Asked Questions

How does this bird genetics calculator work?

The calculator crosses visible mutations and hidden carrier splits across independent loci using Mendelian Punnett square laws, combining autosomal and Z-linked sex-linked inheritance models.

Why can't female birds be split for sex-linked mutations?

In avian genetics, females have ZW sex chromosomes while males are ZZ. Sex-linked traits like Ino, Cinnamon, and Opaline reside on the Z chromosome. Because hens possess only one Z chromosome, they visually display the trait or do not carry it at all; being split is biologically impossible for females.
