Chocolate (b)

Gene

Chocolate (b) is the recessive allele of the rabbit brown gene, TYRP1. Two copies stop black pigment from forming, so the coat is chocolate brown, or lilac when the rabbit is also dilute. One copy is carried unseen under black pigment (B). A stop codon in TYRP1 has been found in chocolate rabbits.

How Chocolate (b) works

Chocolate (b) is part of the Brown series: Black Pigment (B), Chocolate (b). It shows only with two copies and is hidden by Black Pigment (B).

How Much Do Pet Rabbits Cost? Purchase, Spay/Neuter, Setup, and Lifetime Price Guide

How Long Are Rabbits Pregnant? Rabbit Gestation Period and Due Date

That is far longer than the old “a rabbit only lasts a year or two” myth, which came from neglected outdoor hutch rabbits, not from what a healthy indoor rabbit is actually capable of. The gap between those two outcomes […]

Where to Buy a Rabbit: Rescues, Breeders, Health Checks, and How to Avoid the Impulse Buy

The honest answer to where to buy a rabbit is that you usually should not buy one at all before you have looked at a rescue. Rabbits are among the most surrendered pets in United States shelters, after dogs and cats, so shelters and rabbit rescues are often full of healthy animals that are often […]
