How to use this calculator
Open the Coat Colour Calculator and enter values using the units shown.
Formula and assumptions
The calculator uses the visible formula and the assumptions you enter. It does not silently retrieve private records or guarantee a real-world outcome.
Worked example
If each parent has a 50% chance of passing a dominant allele at both loci, the simple model estimates each dominant trait separately and then combines them.

Important limitations
Real coat colour inheritance can involve multiple genes, linkage, epistasis, incomplete dominance, sex linkage and breed-specific variants. This simplified model is not a genetic test.

Frequently Asked Questions
- What does the Coat Colour Calculator calculate?
- Estimate simple offspring coat-colour probabilities from two parent allele pairs using a transparent two-locus inheritance model.
- Can I change the assumptions?
- Yes. Enter values that match your situation and review the displayed assumptions and limitations before using the result.
- Is the result guaranteed?
- No. The result is an estimate and should be independently verified before any medical, legal, financial, academic, engineering or purchasing decision.
