As a result, the rabbits coat will be muted in terms of vibrancy. The agouti coloring is the most prominent. Dark chinchilla removes most of the yellow band. Once you get all those babies weaned and needing cages, grab them here!. These two colours can be diluted to Blue and Lilac, respectively.

As a general rule, The color of a rabbit is determined by the presence or absence of pigment in skin and hair. How Cold is Too Cold? Each parent donates one of a pair of each type of gene to its offspring. To express how genes will function and create variety, an underscore is used to separate gene sequences, signaling how and why differentiation occurs: So, although the role of the dominant genes is apparent, uncertainty lies in between, and there is no way of predicting a genetic blueprint without the second code letter. 4 Collaborative Innovation Center for Genetics and Development, Fudan University, 2005 . The c(h) allele is, therefore, a recessive gene. Unless you know the genetic make-up of the parents, it is not possible to tell what the second gene is on an agouti or tan without test breeding. This type of coloration was once quite rare, but it has become increasingly popular in recent years due to its unique look. The rest of the color genes are still present, but they are just not detectable to the naked eye. Recommendations for choosing your breeding pairs to improve color and avoid disqualifications. An example of data being processed may be a unique identifier stored in a cookie. Double-coated rabbits will have a more recessive coat color, while single-coated rabbits will be more likely to express their dominant coat color. A rabbit is fertile all year round. With so many different rabbit colors available, it can be hard to keep track of what color your rabbits will be. Chart of 144 Rabbit Coat Colors And Their Genotypes Below is the most extensive color family chart on this website. 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). Be aware that if you want to consider two genotypes, e.g., A and B, the Punnet square becomes a 44 table, and three genotypes require an 88 table, making the genetics calculations very tedious. The fundamentals of rabbit coat color genetics are based on just FIVE basic genes, or chromosomal positions (loci), that code for the color of the rabbit's coat. This mutation results in a loss of pigment cells in the hair follicles, which produces the characteristic patched appearance. There are many different alleles that can produce a wide variety of colors in rabbits. While the exact origins of the harlequin pattern are unknown, it is thought to have originated in France sometime during the 19th century. When a rabbit has full extension, it tends to look the same color all over, such as with a blue rabbit. The first variant is, cchd, is (dark) chinchilla. So, instead of AA and Aa, we could write A_. Each line on the chart contains one color family. Put a thin layer on the bottom of the litterbox, then fresh hay on top. Rabbits usually give birth to a litter of six bunnies. This guide assumes a knowledge of basic genetics. A rabbit's pregnancy lasts 31 to 33 days. Owners will also spot a distinctive triangle in a tan rabbit at the nape of the neck. Blue & White: As mentioned before, blue rabbits have grayish-blue fur instead of true blue fur. The ticking may also appear longer. Spots on either side are also OK. Markings that look like they have single white hairs scattered through the colored parts are NOT desirable. Save my name and email in this browser for the next time I comment.

The books vs. e-books calculator answers the question: how ecological is your e-book reader? Depending on the species, a single rabbit hair might have as many as five distinct bands of color on it. 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). There are other colors that are also fairly common, such as black and brown. Ch = Himalayan [BB] (with an added temperature-sensitive feature that prevents pigment from forming on the hairs when the follicles are warmest. 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. There is also an excellent description of rabbit coat color genetics by Laurie Stroupe Of The Nature Trail Rabbitry. There are no color rings or bands on the hair shaft either. The genotypes are listed with dashes for a missing equally dominant or less dominant gene. The two colors known as REW (ruby-eyed white) and BEW (blue-eyed white) are not actually self colors (see below). The alleles (variants) for each gene are what give rise to the different colors we see in rabbits. The length of a rabbits coat does not affect their color genetics, as the pigment granules remain the same throughout the species. Sometimes a phenotype will imply a certain combination of genes but the actual genotype is different. Rabbit coat color is primarily determined by five genes. You have a few possibilities to determine rabbit color: Set the above parameter to "yes" if you want to include steel, harlequin, broken, etc., genes. ej = Japanese [ not accepted in REX [excpet for tri-color]; responsible for harlequin patterns] This allele is also affected by external temperatures, so that colors tend to fade in the summer and become more intense in the winter. There are different breeds of rabbits, so if you are wondering at what age a rabbit can get pregnant, it will heavily depend on the species. The Dominant Black (Ed) makes agoutis look like blacks. Multiple babies are called bunnies or kits. While sometimes thought of as a color, the albino gene is really the absence of color. 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 genotype is the combination of alleles (genes) that determines an individuals phenotype (physical appearance). All you need to do is plug in the date your doe was last exposed to a male. So, A_ has a 75 % chance, and aa has a 25 % chance of occurring. The Rabbit Breeding Color Calculator app is now available for iPhone and iPad. Hi, Everybody! Rabbit Gestation Calculator: Find Out Your Bunny's Due Date Let's explore the five main gene groups used in the rabbit color genetics calculator.

You can also show the ten most probable possibilities of color rabbits or show all of them. A tan (or otter) can be atat or ata, and a self can only be aa. The color variety is achieved by a wide range of intensities, which can even affect a single hair. The self rabbits should be exactly the same color all over their bodies right down to the skin. Further Genetic Resources - EDELWEISS RANCH Insight into little-known genes such as Ed Dominant Black, cch2, and others. There are 5 main groups of color genes, each controling a different aspect of the color and markings. The rabbit must have acquired two recessive solid-coloration genes, one from each of its parents, in order for it to develop a black coat. The complete genotype of the five main gene groups of rabbits' color could be, for example, Aa Bb CC Dd Ee, which is a chestnut color (A_ B_ C_ D_ E_). Let me know if you need anything else. ), Can a Rabbit Die from Eating Too Much? When it comes to coat color in rabbits, there are a few different factors at play.

However, some of the most common recessive colors include blue, chocolate, and lilac. Be sure to check out my hour-long video course on rabbit colors and bunny color genetics! Additionally, a rabbit's pregnancy lasts approximately one month. The dominance relationship for these genes is quite simple: each allele is completely dominant over the ones 'below it (as listed above).
