🎨 Rabbit Color Calculator
Select genotype combinations at the A, B, C, D, and E loci to see the resulting coat color description.
Predicted coat color
Chestnut agouti
This simplified model highlights common phenotypes. Individual breeding outcomes may vary.
How to Use This Calculator
Select genotype for each locus
Use your rabbits’ genetic test results or expected gene combinations.
Review phenotype output
See a plain-language coat color based on classic rabbit genetics.
Plan pairings carefully
Use as a teaching aid—consult detailed genetic charts for breeding decisions.
Formula
Coat phenotype = f(A, B, C, D, E loci)
The A locus controls agouti pattern, B controls black vs. chocolate base, C modifies color expression, D controls dilution, and E affects extension of eumelanin. Dominant alleles mask recessive ones at each locus.
Full Description
Rabbit coat colors arise from interactions across multiple gene loci. This calculator simplifies common combinations to describe likely phenotypes for hobby breeders and students.
For precise breeding plans, consult comprehensive genetic resources covering modifiers such as steel, tan, vienna, and wideband genes.
Frequently Asked Questions
Where can I get genotype information?
Use reputable genetic testing labs or track inheritance from known parent genotypes.
Does this include Vienna or steel genes?
No. This simplified model covers A, B, C, D, and E loci only.
Can two agouti carriers produce a self kit?
Yes. If both parents are A/a, there’s a 25% chance for a/a self offspring.
Why does dilution matter?
The D locus lightens pigments—turning black to blue, chocolate to lilac.
