Rabbit Color Genetics: The B Gene

Lydia's Fudge, self-chocolate doe, genotype is bb.  The red eye is from the flash.  Her eyes are actually brown.
The B gene is the easiest of the rabbit color genes to understand.  All rabbits are either black-based or chocolate-based.  (Even the REWs, which are white, are either black or chocolate.  It's just that the REW (cc) "bleaches" the color out.)

B stands for black.  Chocolate is represented by b.

A rabbit gets one allele from each parent.  If your rabbit is BB or Bb, it is black.  If your rabbit is bb it is chocolate.

Self-black kit, genotype is either Bb or BB
