Rabbit Color Calculator

A simplified prediction for the B gene, where black (B) is dominant over brown/chocolate (b). Real rabbit color involves several interacting genes.

How the Math Works

The Rabbit Color Calculator uses a Punnett square to predict coat color based on the B gene, where black (B) is dominant over brown (b). By inputting the alleles of both parents, the tool calculates all possible combinations of offspring genotypes (BB, Bb, bb) and determines their phenotypic probabilities. For example, if both parents are heterozygous (Bb), the Punnett square reveals a 25% chance of brown (bb), 50% chance of black carriers (Bb), and 25% chance of fully black rabbits (BB). This mathematical model relies on Mendelian inheritance principles to forecast genetic outcomes.

Practical Applications

To use this calculator, enter the genotypes of the two parent rabbits (e.g., BB, Bb, or bb) into the designated fields. The tool then generates a visual Punnett square and breaks down the probability of each coat color in the offspring. For instance, crossing a black rabbit (BB) with a brown rabbit (bb) will show 100% black offspring (Bb). This simplifies complex genetic predictions, allowing breeders to plan litters with desired coat colors without manual calculations or prior genetics expertise.

Day-to-Day Use

This calculator streamlines breeding decisions for rabbit enthusiasts, pet owners, and agricultural professionals by providing quick, accurate predictions about offspring coat color. Hobbyists can strategically pair rabbits to achieve specific color outcomes, while breeders can optimize their programs to produce marketable or preferred traits. Additionally, it serves as an educational tool for teaching basic genetics concepts, making abstract scientific principles accessible for students, teachers, or anyone curious about heredity in a relatable, hands-on context.

Worked example

Bb × Bb → 75% black, 25% brown.
