What This Rabbit Color Calculator Helps You Do
This page gives a readable introduction to rabbit color inheritance by combining parent genotypes into a simplified offspring distribution across major phenotype families.
It is best used as an educational breeding aid when you want a quick sense of likely outcomes without modeling every rabbit color gene in depth.
How to Calculate Rabbit Color Calculator
- Enter the sire genotype: Type the simplified genotype for the A, B, D, and E loci in the order A B D E.
- Enter the dam genotype: Use the same simplified four-locus format for the second parent.
- Generate offspring combinations: The calculator enumerates gametes and combines them into all possible offspring genotypes.
- Review phenotype groups: Offspring are grouped into simplified major color families for a quick breeding estimate.
Rabbit Color Calculator Formula
| Variable | Meaning | Unit |
|---|---|---|
| A locus | Agouti versus self pattern locus | AA, Aa, or aa |
| B locus | Black versus chocolate pigment locus | BB, Bb, or bb |
| D locus | Dense versus dilute pigment locus | DD, Dd, or dd |
| E locus | Extension versus non-extension locus | EE, Ee, or ee |
Use the worked examples below to check how the formula behaves with real values. If the result looks unexpected, verify the unit assumptions and the meaning of each variable before interpreting the answer.
Worked Examples
- Sire: aa BB Dd EE
- Dam: aa Bb dd Ee
Result: Offspring are split among black self, blue self, and related dense/dilute self variants.
Dilution and chocolate carriers increase phenotype diversity even when both parents are self-pattern rabbits.
- Sire: Aa BB DD Ee
- Dam: Aa bb Dd Ee
Result: The offspring include agouti, tort, black, chocolate, blue, and lilac family outcomes in different ratios.
Mixed A, B, D, and E alleles broaden the phenotype spread quickly in a simplified model.
How to Interpret Your Results
| Range | Meaning | Action |
|---|---|---|
| More than one major phenotype family | Both parents carry recessive or contrasting visible color alleles. | Expect more variation across the litter. |
| Mostly one phenotype family | The parental genotypes are relatively uniform for the modeled loci. | The litter is more likely to cluster around one major color group. |
| Simplified genotype model only | Not all rabbit color genes are represented here. | Use this result as an educational estimate, not a full pedigree-color prediction. |
