How to Use the Coat Color Calculator
This tool predicts the coat color probabilities of offspring based on the genetics of two parents, using a simplified Mendelian inheritance model (B = black dominant, b = white recessive).
- Select Parent 1 Genotype: Choose from the dropdown: Black (BB), Black (Bb), or White (bb).
- Select Parent 2 Genotype: Choose the second parent’s genotype from the same options.
- Click "Calculate Probabilities": The tool runs a Punnett square analysis using the selected alleles.
- Review Results: You’ll see:
- Percentages for each possible offspring genotype (BB, Bb, bb).
- Combined percentages for Black Coat (BB + Bb) and White Coat (bb).
Note: Genotypes are case-sensitive: "B" = black allele, "b" = white allele. No other input formats are needed.

Frequently Asked Questions
It uses a Punnett square to compute the probabilities of offspring genotypes (BB, Bb, bb) based on the parental genotypes you select. Black coat is dominant (B) and white is recessive (b).
BB and Bb result in black coat; bb results in white coat. B represents the dominant black allele, b the recessive white allele.
This is a simplified model for educational purposes. Real coat color genetics can be more complex, involving multiple genes and modifiers.
