Genetic calculator.

Set what each parent carries and we'll work out the odds for every offspring outcome. Covers recessive, co-dominant and dominant genes; line-bred (polygenic) traits don't follow fixed odds and are left out.

Odds assume each gene is inherited independently and describe each egg or offspring separately — a 25% outcome does not guarantee one in every four animals.
