The five basic genes are: A: Agouti hair shaft pattern (or not) B: Black (or chocolate) C: Complete color (or shaded or albino) D: Dense (or dilute) color E: Extension of color (or its limitation or elimination) . The law of segregation says that the two components for a characteristic, which are present together in a heterozygous person (Bb), do not mix and are instead separated and supplied separately during gametogenesis, as opposed to the other way around. No more smell! I gather this would result in both certain genotypes with their probabilities, but also it could show other possible genotypes that could confirm what the unknown allele is, should an offspring show up to matching it. However, this calculator should not be considered a substitute for a veterinarian. Heres an illustrated tutorial on using breeding squares. . Images are property of Hook's Hollands.

Agouti is the most common base color and is characterized by having bands of light and dark fur on each individual hair shaft. In rabbits, there can be as many as five bands of color on a single hair. Or, the bunny could be born with black fur if one parent has the black gene and the other parent has no color gene (which is common in rabbits).
