![]() If you do have a male calico, however, a healthy diet, exercise, and lots of love and attention can help him live a longer and happier life. XXY Syndrome renders male calicos sterile and can be the root cause of many other health problems. We will leave you to decide how you feel about that, but the reality is that, due to genetics, 99 of calico cats are female, and it is believed that only 10 of all cats are long-haired because the long hair gene is recessive just do the math. This can produce a male calico.Ībout one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities. ![]() There is one exception: A genetic anomaly called XXY Syndrome, which occurs when the male cat has two X chromosomes and one Y chromosome. They'll only express either black or orange, but not both. To manage these two sets of color code, the female embryo will shut down one X chromosome in each cell, resulting in the black and orange variations in a calico's coat.īecause male cats have one X chromosome with code for black or orange and one Y chromosome without any color genes, they cannot technically be calico. expressing both black and orange coloration. They are quite the feline and are characterized by irregularly shaped. Calico cats are usually an interesting group but not always under the umbrella of Domestic Short Hair or Long Hair. The tortoiseshell cat has black and orange fur, in a mottled pattern. Only if the cat gets one orange-coded X and one black-coded X will it be calico. Although the standard pattern is splotches of color, if a calico’s mother, father, or both are tabbies, striping can occur. Calico cats are almost always female due to the chromosomal makeup that determines the color variation of the coat. A calico cat can come in a wide array of coat patterns, and no two really ever look identical. By chance (and depending on the colors in the parents) both X chromosomes may carry the black code or both may carry the orange code, in which case the cat would have those markings. The X chromosome also carries the coding gene for the black and orange colors in a calico's coat.įemale calico cats have two X chromosomes and therefore have two chromosomes with color code. Each cat has a pair of sex chromosomes with the possible combinations of XX (female) and XY (male). ![]() The sex chromosomes (X and Y) determine whether a cat will be male or female. It's a fact that 99.9 percent of all calico cats are female due to the unique chromosomal makeup that determines the color variations in their coats. ![]()
