Tri colored cats all female?
I suppose I could check Google but I'm here so...
Someone at the cat show said that all tri-color (or tri-colour for my British friends) cats are female, or, if male, are sterile. Seems odd but he was showing his purebreds so maybe he knew what he was talking about. Does white count as a color? |

These colors are sex linked, though a tourtose shell mated to a red tabby can produce red tabby females (I once had three tamed feral red tabby and white sisters - there motehr was calico, and they had an unusual white mark that matched that of the neighborhood red tabby male).

Someone at the cat show said that all tri-color (or tri-colour for my British friends) cats are female, or, if male, are sterile. Seems odd but he was showing his purebreds so maybe he knew what he was talking about. Does white count as a color? TRUE tricolors [1] are almost always female because it requires 2 X chromosomes. Male tricolors are therefore XXY. See this for a pretty good explanation (and source of below quote): http://www.fanciers.com/cat-faqs/tricolors.shtml [1] "A true tricolor must have one of its colors derived from the red gene -- either red (orange) or cream (kind of a light, orangy beige, not unlike the color many people call "ginger"). If it does not have one of these two colors, it is not a true tricolor. The second color must be white, and the third color must be black, blue (a blue-gray), chocolate, lilac (a pale rose- beige), cinnamon, or fawn (a pale buff color). Black and blue are by far the most common." -- -- ~kaeli~ Frisbeetarianism (n.), The belief that, when you die, your soul goes up on the roof and gets stuck there. http://www.ipwebdesign.net/wildAtHeart http://www.ipwebdesign.net/kaelisSpace |

Seems odd but he was showing his purebreds so maybe he knew what he was talking about. Does white count as a color? Tortoiseshell and tricolor (calicoin America) cats are almost always female. The very few male exceptions -1 in approx 200, I've heard - are almost invariably sterile, and it's genetic. Here's a convoluted description of why. Lotsa luck reading it! ___________________ "The term tortoiseshell cat refers to a coloration pattern caused by a combination of specific genetic traits. It is not a specific breed of cat A cat breed is an infrasubspecific rank for the classification of domestic cats. A cat is considered to be of a certain cat breed if it is true breeding for the traits that define that breed. Only three percent of owned cats belong to a cat breed, and an even smaller percentage of those are suitable as show cats. A breeding certificate proves that a cat belongs to a cat breed by showing the cat's pedigree back to at least four generations. The whole concept of cat breeds is a relatively new one. Two hundred years ago there was no such thing. Today there are almost a hundred cat breeds. Varieties of domestic cat can also be identified by characteristics other than breed. The tortoiseshell markings appear in many different breeds. The coats of tortoiseshell cats are a mixture of colours. It is often reserved for cats with coats that look like black and orange patches, while calico cat is typically two-thirds white, with orange and black patches on their backs. Their coats may also combine red or ginger, and occasionally silver or ginger tabby patterns. The size of the patches can vary from a fine speckled pattern to large areas of colour. Cats with a basic white colour and red and black patches are known as tortoiseshell-and-white in Britain, or, in the United States, calico. Coat coloration in cats is complex. The genes involved include the Orange gene, O, which in its dominant form, O, produces orange fur, and in its recessive form, o, produces black fur. For a cat to be calico, it must simultaneously express two genes, O and o, which are located at the same location on the X chromosome A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most common sex-determination systems in animals involve a genetic mechanism based on the chromosomes of that organism. However, other systems can involve other variables such as temperature. The details of some sex-determination systems are not yet fully understood. Occasionally a male is born. These have Klinefelter's syndrome Klinefelter's syndrome is a condition caused by a chromosomal abnormality in males (specifically, a nondisjunction); sufferers have a pair of X sex chromosomes instead of just one. The XXY chromosome arrangement is a common genetic abnormality, occurring as frequently as 1 in 1,000 male births, but the symptoms that may result from having the extra chromosome are less common. Because of this extra chromosome, individuals with the abnormality are usually referred to as "XXY Males" rather than as "suffering from Klinefelter's syndrome and are almost always sterile." _______________________ http://encyclopedia.thefreedictionar...iseshell%20cat Aren't you glad you asked? g |

Gee. Just think. NONE of this valuable information would have been known if

I can't stand to go into an animal control building where they house unwanted cats and kittens until they find homes for them, or euthanize them. The odds of the latter fate are high enough,even with conscientious cat-owners (you call us "animal mutilators") neutering and spaying their animals. Imagine the numbers of little tragedies if no one did. |
