This third and final color pattern describes rabbits that have underfur with silver markings, which is also apparent under the tail, around the eyes, and in the nostrils. At least some of these variant forms are temperature sensitive - the higher the temperature, the more effective they are (i.e, the lighter the color). These genes are designated with the letters A, B, C, D, and E, which makes logical sense given their location on the chromosome. The various color genes found in rabbits are: A, B, C, D, E, En, Du, Si, V, and W. 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) Always consult a veterinarian if you believe your pet may be pregnant. If you need a refresher, try: Dr. Dennis O'Neil, Behavioral Sciences Department, Palomar College, San Marcos, California, This site has a well-written introduction to genetics and to rabbit coat colors at Aurora Rabbits: Raising Rabbits.com. In that case, it is handy to use the Punnet square, which we will show only for the A gene for simplicity: Eventually, you can see that the offspring will have the AA genotype with 25 % probability (one case), Aa with 50 % (two cases), and 'aa' with 25 % (one case). They are A, B, C, D, and E. Thank goodness for small favors. . Rabbit Genetics | The Nature Trail The E/e gene controls whether the basic color on the rabbit (black, blue, chocolate, or lilac) is extended all of the way to the end of the hair shaft or whether the basic color stops and another finishes the hair shaft (such as the orange color on the back of a black tortoiseshell). Bear with me while I expand the lists to allow for more colors. The alleles for this gene are C, c(chd), c(chl), c(h), and c, in the order of dominance.

Most of my "rabbit math" is based on that cycle. World Rabbit Science, 2, 21-24. Harlequins are characterized by having two large patches of color, one on each side of their body. The harlequin pattern is caused by a mutation in the gene that controls coat color. Note that the names of different colors vary a little from breed to breed, so feel free to ask us if you have a question about a color. I'm a bit unclear on the naming nomenclature for that. There is also an excellent description of rabbit coat color genetics by Laurie Stroupe Of The Nature Trail Rabbitry. Rabbit Color Genetics Calculator Although the vibrancy will fade close to the skin, there will be no additional colors as found with wild agouti rabbits. Such a rabbit has never been seen in person or on film, but it may exist somewhere in the world! Integrated advice from leading breeders and judges. If you buy a pet rabbit described as chestnut or chinchilla in color, then these rabbits are also a type of agouti, with their color still closely related to their wild cousins. An albino rabbit can be identified by eyes that are red and pink, which occurs because there is an absence of pigment in the eyes that would otherwise obscure the red blood vessels. We will go through them in the following instructions: The first mode allows you to select the colors of a sire and dam from a list of 121 rabbits shown in the color chart based on the The Nature Trails article. The Dominant Black (Ed) makes agoutis look like blacks. Indeed, every hair is made up of one single color.
