Bird genetics & inbreeding calculator — Birds Evolution
Plan breeding pairs with mutation predictions and calculated inbreeding. Birds Evolution combines both tools with your bird records, so genetic planning belongs alongside the breeding history of your flock.
Open or install Birds EvolutionPredict offspring mutations before breeding
Enter the mutations of the male and female to see possible offspring outcomes and their probabilities. Results are presented separately for young males and females. This helps breeders evaluate a proposed cross before forming a pair.
Configure mutations for your species
Birds Evolution supports dominant, autosomal recessive, sex-linked and co-dominant inheritance, including combinations. Import mutations from the built-in database or configure your own for a species. The calculator is not restricted to a single fixed list of colour names.
Calculate inbreeding from recorded ancestry
Birds Evolution calculates an inbreeding percentage and identifies common ancestors. Use this alongside the family tree when evaluating a breeding pair. Accurate ancestry records matter: missing or incorrect parents limit what any pedigree-based calculation can establish.
Keep predictions and breeding records together
Record the parents, review the mutations for the species, inspect the predicted outcomes and check shared ancestry. Continue with the same breeding records to follow clutches and individual eggs through hatching. Predictions describe probabilities, not a guaranteed result for each clutch.
Questions and answers
Does Birds Evolution predict genetic mutations?
Yes. The genetic calculator predicts offspring mutations from the parental mutations, with probabilities displayed separately for males and females.
Can I configure mutations for different bird species?
Yes. You can import mutations from the built-in database or configure your own mutations per species, using the supported inheritance types.
Does Birds Evolution calculate inbreeding?
Yes. Birds Evolution calculates an inbreeding percentage using recorded ancestry and shows detailed common ancestors. It also provides printable genealogy and pedigree views.
Are mutation prediction and inbreeding calculation the same tool?
No. Mutation prediction evaluates possible inherited outcomes from a cross. Inbreeding calculation evaluates shared ancestry in a pedigree. Birds Evolution provides both capabilities for breeding decisions.
