The other non-basic genes play a role in modifying colors and patterns, meaning that rabbit fur can be many different levels of vibrancy. Color My Litter online interactive color calculator that provides the best estimates of color distribution in a potential litter of kits and percentage probability of colors. I tend to think of the A locus as the Agouti locus, that it is just the banding and not the actual color unless it is fully expressed. Its not impossible to find agouti fur in pet rabbits, though the pattern does vary a bit more and tends to be described as chestnut. It may not display this or other websites correctly.

The rabbit color calculator will show you selected color genes for sire and dam that we use to solve the Punnet square. Most of my "rabbit math" is based on that cycle. (Overweight Rabbits), How Well Can Rabbits Hear? . In total, the genome data came from 79 samples, including 33 samples of wild rabbits and 46 samples . Thus, it takes only one broken pattern gene to produce a broken. These silver markings appear in the same way as white fur does on agouti rabbits and can vary in shade and color, appearing white and cream in many tan rabbits, but as dark as orange in some. As a result, shorter hairs appear darker (and also why long-haired varieties look faded). alculator# Multiple babies are called bunnies or kits. While these genes are many, there are five main gene groups that are responsible for the vast majority of color variations: A, B, C, D, E. If you want to take into account much more genes, say yes to the include additional genes question in the rabbit color calculator. Four rows of full-extension colors are followed by the corresponding four rows of non-extension colors. All genes come in pairs. If a BEW vv is bred to a non-BEW VV, the young will be 100% Vv BEW carriers and tend to be marked with white. Here you can find more info on rabbit breeding.

The rabbit color calculator uses the algorithm that finds the combination of sire's and dam's genes and determines what genes and color their offspring may have. The two colors known as REW (ruby-eyed white) and BEW (blue-eyed white) are not actually self colors (see below). e = Non-Extension [helpfulfor Red]. Additionally, the behavior of a doe when introduced to a buck will indicate whether she is ready to mate or not.
