For the average pet parent, it's a good idea to have your kitty spayed or neutered to avoid starting any kind of breeding program in your house. For example, Munchkin cats are super cute (I mean, look at them! This website uses cookies so that we can provide you with the best user experience possible. Whether or not a red can produce as a tabby will depend on whether it is a true tabby with a tabby or shaded parent or whether it is a red with ghost tabby markings and neither a tabby nor a shaded parent. must have a parent which displays a dominant color (see #21). When PATTERN is used, it refers to pattern only (tabby, shaded, smoke, etc.). For further information on feline genetics, we recommend the following: The information contained on this page is also available in a PDF format of our printed pamphlet. Join us at Companion Cat World and get a membership card, savings, and fun events! DNA tests can provide information, such as disease risk, best guesses at breed ancestry and even your furball's similarity to certain wild cat species. Essentially, this means that the DNA that helps make up cats can be affected at some point in their development that makes the cat more likely to develop diseases. When both are affected, the statement will contain the term COLOR/PATTERN. The variations among cat coats are physical properties and should not be confused with cat breeds. So many identified genes are involved in making every feline just as special and unique as they are. Cat genetics describes the study of inheritance as it occurs in domestic cats. Why compare cat genetics in the first place? These are anxious or highly strung cats. The characteristic cannot be transmitted from one generation to the next without showing that characteristic in each generation. Genetics for solid white cats can affect the possible color/pattern of expected kittens in that the white parent may be masking the color/pattern needed to produce this result. A shaded parent can produce a smoke offspring, but a non-shaded (smoke) parent cannot produce a shaded offspring unless bred to a shaded (see #21). A simple blood test has been developed to detect this genetic mutation, and the prevalence of PKD has been dramatically reduced by testing cats before breeding. Interestingly, white kittens may have a small spot of color on top of their heads when born. Other health conditions, like asthmatic or cross-eyed Siamese cats, are disproportionately common in a specific breed, but a single gene for them has not yet been identified. Delicious roasted chicken and rice in a mouthwatering sauce. The Tech Museum of Innovation at Stanford University points out that if you lined up a sequence of one hundred letters of genetic code, only ten would differ between you and your cat. The study found that all of the cat breeds tested showed genetic links between human directed aggression traits and shyness traits. Cat mutations generally show up randomly as recessive genes come out and different breeds of cats are mixed. We test for genetic markers, reporting on mutation carrier status and predisposition to different diseases. The spot of color may be visible for several months, but often disappears as the kitten matures. If you want to have your cat's genes tested, there are companies that offer genetic tests that will offer breed ancestry, health and wellness recommendations. The color/patterns found in the pedigree of a kitten will NOT always directly affect the color/pattern of the kitten. A dominant characteristic (all dominant colors and patterns such as shaded, smoke, white, tabby, bi-color, etc.) Many cat breeds originated from single gene traits, such as folded ears of the Scottish Fold and dorsally curled pinnae of the American Curl, and then later developed into a more conformationally unique breed. Studying cat genetics not only helps us to care for our feline friends better, it helps us understand our own genetic disorders and develop new ways to resist and treat diseases that have a genetic component. We hope this cat coat genetics guide provided a clearer view into the fluffiness of your kitty. Your cats won't tell you when they're sick. The basis of feline genetics relies to DNA within the feline karyotype due to inherited mutations or mutations due to environmental or exposure changes. If you are planning on breeding cats, knowing the genetic predispositions of the breed and having breeding animals tested for genetic disease can ensure that you will not be forcing cats to pass on any genetic mutations to their offspring. Furthermore, Ragdolls and Maine Coons showed a … (Ii) Using the square, we can concur that Chloe and the father were carrying the recessive allele for blue eyes, and the rest of the kittens inherited the hazel-eye trait. A shaded cat must have at least one parent that is a shaded (see #21). Phenotype vs. Genotype. The masked color/pattern must be determined, based on the white’s pedigree and the offspring produced in a controlled breeding, in order to effectively predict the color/pattern of the expected offspring. The hidden traits aren’t visible in your cat’s appearance but may get inherited by the cat’s children. Blindness. Hallmarks of Genetic Diseases. There may be other Polydactyls that appear in different gene populations that are inherited differently. Notes: (1) Rarely, a cat is born with two X chromosomes and one Y. For example, a Siberian could wear point coloration, the stereotypical coat of a Siamese. Knowing the genetic makeup of every hair on your cat's head is fascinating, but it's also important to treat her as an individual, with needs and personality quirks that you and your vet, not a breeder, know best. Potential and current pet parents should be aware of the concerns that come with caring for a specific breed. Your use of this site is subject to the terms of our Legal Statement. A trait is some aspect of an organism that can be described or … Two longhair parents cannot produce a shorthair kitten. Both of your cats have special genetic characteristics unique to calico and tortoiseshells, meaning that they have the genes for both orange fur and non-orange fur. Find out why a cat scooting on carpet could be a sign of inflamed anal glands and what you can do to help relieve your cat's agitation. Cat Coat Colour Genetics AGOUTI. cannot produce an offspring of a dominant color (black, red, etc.). The Cat Fanciersâ Association, Inc. is proud to be an equal opportunity employer. Curious why your cat keeps sneezing? Like humans, cats can have vitiligo, a condition that causes the loss of … A locus, also known as the agouti, affects the distribution of both pigments, eumelanin and phaeomelanin. The University of California Davis Veterinary Genetics Laboratory also provides genetic testing for specific feline health conditions. The wild type gene of the A locus, A gene, is dominant in the series and it causes the agouti shift phenomenon, resulting in hairs to be differently pigmented at the tips and at the roots, such as in tabby stripes. To obtain any of the red or cream color/patterns in female kittens, the sire must be one of the red or cream color/patterns PLUS the dam must in some form demonstrate red or cream (see #21). What Your Cat's Genetics Say About Her | Hill's Pet, The Tech Museum of Innovation at Stanford University, University of California Davis Veterinary Genetics Laboratory, Is Your Cat Scooting on the Carpet? Manx cats are are a good example of a single gene with two phenotypes: dominant tailless and recessive lethal. Because females carry two X chromosomes and males carry only one X chromosome, the likelihood of a cat receiving both black and red genes is much higher with a female cat. Copyright Information | Privacy Statement | Contact CFA | Contact Webmaster. Discover the underlying reason, such as a digestive issue or anxiety, and learn if it's truly a problem. In doing so, you can gain information about your cat's ancestors and determine if your cat has any of the gene defects that are associated with inherited diseases. The chocolate or lilac gene must be present in both the sire and dam’s pedigree in order to produce chocolate or lilac offspring. The Skittish Cat. Cat genetics are the blueprints that dictate everything from coat color, to personality, to the number of toes. This color should be noted as it is the color that the white is masking and the color that the cat will breed as when an adult. Parti-color cats (blue-cream, tortie, calico) are almost always female, but males can and do occur occasionally (and are not always sterile). As in breeds of other species, a disease or health concern can sometimes be considered part of the cat’s desired phenotype. Your pet's genes are the reason why Siamese cats are so talkative, ragdolls are cuddly, Sphynx cats are hairless and Persians have smushed faces. The primary gene is the one that gets manifested in the cat’s appearance. Precisely balanced nutrition with the delicious taste of savory minced ocean fish to help fuel the energy needs of cats during the prime of their life. Genetic testing helps you know your cat inside and out, and provide the best environment and care so that you can have a long and healthy life together. She enjoys camping with her family, skiing, SCUBA, and participating in triathlons. PKD is a simple autosomal dominant genetic disease, which means that it is passed down to offspring even if only one of the parents has the mutation. This suggests that whoever the father figure cat was heterozygous for the blue eye allele. Genetic Traits Part 1: Cat Genetics Using cats as the subject for examination, determine as much as you can about their genes. Progressive retinal atrophy (PRA), a disease that causes blindness in mid to late life, is … “The Genes of Cats” in The Book of The Cat, Summit Books, New York, l980.

Be proactive about your cat's health. The color of the female kittens in a litter will always be either a combination of the sire’s and dam’s colors, or the dilute form of those colors (see #21 & #24). Some diseases, such as polycystic kidney disease in Persians and hypertrophic cardiomyopathy (heart disease) in Maine coons and ragdolls, are known to have a genetic component, writes International Cat Care. Various cat breeds have been around long enough that their distinguishing About our Ads. Attributes of the phenotype can be desirable or undesirable. Cat Genetics 1.0: The Basics Cat owners, cat breeders and veterinarians with cat practices should all have a basic understanding of cat genetics. However, the European wild cat (Felis silvestris) may also have contributed to the genetic composition of the domestic cat by hybridizing with the African wild cat. But, for now, knowing the basics, I dare you to ever look at a calico cat the same way again. If you disable this cookie, we will not be able to save your preferences. Whether these characteristics have much truth to them or not, though, according to the Smithsonian Institution, "A 2002 study in the Journal of Applied Animal Welfare Science, for example, found that black cats and brown cats were the least likely to be adopted.Dark cats were also more likely to be euthanized. In feline husbandry it can predict established traits (phenotypes) of the offspring of particular crosses. Understanding how is challenging because many genes are involved. The male offspring in a litter will always be either the color of the dam (or one of the colors in the case of parti-colors) or the dilute form of the dam’s color. While many diseases are multifactorial (meaning they have more than one cause, which can be both genetic and environmental), researchers have identified through genetic sequencing of chromosomes that cats have genetic mutations that predispose them to developing specific diseases. You can find out more about which cookies we are using or switch them off in settings. That means they can have different combinations of versions. Delectable chunks with tender chicken smothered in a rich gravy. This change in their genetic makeup is kind of like an error in their code. We provide evolutionary assessments of the feline protein-coding genome, population genetic discoveries surrounding domestication, and a resource of domestic cat genetic variants. The Cat Fanciers’ Association, Inc.260 East Main Street, Alliance, OH 44601Phone: (330) 680-4070  /  Fax: (330) 680-4633. Anal Glands May Be the Culprit. “Feline Genetics” in A Standard Guide to Cat Breeds, McGraw Hill, New York, l979. By providing good nutrition and a healthy environment and taking genetics into account, you can positively shape your cat's health and well-being. This has been very helpful in the case of polycystic kidney disease (PKD) in flat-faced cats. One notable exception is the colorpoint gene, which can carry through a number of generations (see #21 & #24). “In cats, the red and black colors are on the X chromosome,” Hicks explained. See the statement on dilutes for more information (see #21 & #24).

Learn some potential causes of her sneezing fits, including possible irritants and ties to dental issues. Cat coat genetics determine the coloration, pattern, length, and texture of feline fur. The primary trait has a 75% chance of getting passed on, with a 25% chance that one of the hidden traits will pass on instead. A cat may display the coat of a certain breed without actually being that breed. Two parents, but you already know that. A cat displaying a dominant color (black, red, tortie, etc.) A cat’s appearance, its phenotype, is a combination of visible traits and morphologic types. Dwarfed cats often have joint problems and abnormally curved spines that can predispose them to herniated spinal discs. A kitten’s pattern can be inherited from either parent. Intuitively it is quite simple, and it’s all about two. A white cat breeds as both a white (which you see) and a masked color (which you don’t see) and can produce based on both white and the unseen color/pattern. A (non-silver) tabby must have at least one parent that is either a shaded or a tabby. This means that every time you visit this website you will need to enable or disable cookies again. The number to remember… (They're all born with blue eyes.) Vitiligo, Spots, and Albinism. Another important fact is that some versions are stronger than others. Your pet's genes are the reason why Siamese cats are so talkative, ragdolls are cuddly, Sphynx cats are hairless and Persians have smushed faces. We also share 98 percent of our DNA with chimpanzees and 80 percent with cows (and more than 60 percent with bananas, according to the National Human Genome Research Institute, so maybe we shouldn't get too excited). © 1995-2021 The Cat Fanciers' Association, Inc. It is only possible to fully know the genetics of pure-bred cats. A bi-color must have a bi-color parent (see #21). If a mutation occurs which significantly alters the anatomy of the cat, there is usually great debate on whether it should be allowed to die out or if the mutation is harmless enough to encourage breeding. Temperament Due to the fact that chimerism is not seen as a breed, the affected felines don’t come with an identical personality trait or standard characteristics. This means that fearful behaviour and aggression towards humans are linked. For more information, please refer to books on the subject. International Cat Care believe that whenever genetic tests are run on cats for the selection of breeding stock, the gene test result should be linked to a method of permanently identifying the cat that has been tested (eg, a standard, internationally recognised microchip number), and that a vet should collect the sample (blood sample or cheek swab) so that the identification (microchip number) can be …
