GENE POOL - The total of all genes in a feline population.
GENE CONVERSION - Interaction of alleles that leads to unequal genetic exchange during meiosis. Refers to a process of non reciprocal transfer of genetic information.
Since the gene pool was small, breeders outcrossed to other breeds to maintain genetic diversity. Siamese, Havana Browns, American Shorthairs, and domestic shorthairs were among the breeds used.
A broader gene pool came about through further importations from Japan. Ms. Freret imported cats from Dr. Masurori Kojuma, a Tokyo Veterinarian, and Mrs. Alan (Connie) Bath, who was the wife of the Assistant Naval Attache to the Tokyo Embassy.
In 1986, the gene pool was closed to Siamese and American shorthair outcrosses. However, Abyssinians are still used in ocicat breeding programs and will be until January 1, 2005. This will help keep the gene pool large and healthy.

The Havana Brown is a fairly recent breed of cat, its development having started in England in the 1950’s by a group of fanciers that managed to isolate the gene pool of a self-brown cat.
The early development of the breed in all countries where the LaPerm was introduced has included a phase where outcrossing was used frequently to develop a sustainable gene pool.
To maintain the Persian body type, coat, and diversified gene pool, it is necessary to breed back to the Persian. Roughly 50 percent of kittens from Exotic/Persian matings will have long hair if the Exotic parent carries the recessive longhair gene.
breeders seek out non-pedigree cats closely resembling the correct body type, continuing using the kind of cats which composed most of the original foundation stock for the breed and helping to maintain genetic health by using the widest gene pool ...
Developed over more than twenty years, Australian Mist have a large gene pool, derived from over 30 foundation cats, half Burmese, and a quarter each Abyssinian and Domestic.
Because of the small gene pool and because additional Maus were almost impossible to obtain from Egypt, a certain amount of inbreeding and outcrossing were required to continue the breed in North America.
The Singapura, whose name is Malaysian for Singapore, originates from Singapore in South East Asia where the ticked coat pattern and dark brown color are a common local combination recognized as the original gene pool for ticked tabbies.
It is an open and controversial question whether this reflects an Egyptian Mau contribution to their gene pool or whether cats with Mau-like traits are superior barn cats.
When short, stocky longhaired cats from Iran (formerly known as Persia) were incorporated into the gene pool, the breed became known as Persians.
The Russian Blue was designated as an outcross for the new breed and it continued to allow the addition of foundation cats as an important way of developing the gene pool.
The breeder or breeders who initially establish a breed, do so by selecting individual animals from within the groups gene pool that they see as having the necessary qualities needed to enhance the breed model they are aiming for.
Rare breeds are more likely to experience issues with poor health due to the fact that the available gene pool is limited, leading to inbreeding.
Truda Straede says that new domestic and Abyssinian lines have been introduced, thus broadening the gene pool.
The standard states "open registry until sufficient gene pool has been established". The preferable out-cross desired by The LaPerm Society of America is, however, the domestic cat.
Incidence can vary in different parts of the country, probably because of the gene pool present in a particular area. The most common problem among cats is heart muscle disease (cardiomyopathy) and it causes no end of trouble.
A young breed, the Devon Rex is carefully crossbred to American and British Shorthairs in order to enlarge and strengthen the gene pool ...
Whatever the precise historical origins of the Manx breed are, the confinement and isolation of cats on the Isle of Man inevitably led to in-breeding within a small feline community that had an extremely restricted gene pool.
The Balinese was developed from a recessive gene in the Siamese gene pool. This recessive gene was for long hair. These longhaired kittens appeared in purebred Siamese kitten litters in the 1940s.
World War II nearly ended this breed's existence, like so many other breeds in England, and Siamese had to be used to broaden the gene pool. As a result, it took years of careful breeding to restore the Russian Blue's plush coat.
These cats look much like any other domestic cats except for their shortened legs, with the front legs slightly shorter than the hind legs. As the gene pool for these cats remains open to any non-purebred, consistency of type is yet to be achieved.
The future of these cats is in question because the gene pool is small. The breed is still being developed in the U.S. The Singapura was recognized in championship standing in 1988. In its second season of show it realized an amazing triumph.
Cat breeders recognized the unique beauty of these cats and ensured its survival and the gene pool is now quite large. Currently the popularity of the Snowshoe is increasing throughout America and the rest of the world.
and Canada traced their ancestry to two of the original imports from her Fatima Cattery, but recent importations have enriched and broadened the available gene pool for breeders. Recognition for championship competition came in 1977.
1980 it was recognized for championship competition by CFA stimulating much needed interest in the breed. Recognized world-wide, many fine "Brits" are still imported today from England, Ireland, New Zealand and Australia to help widen the gene pool ...
the Burmilla programme and in most of the major groups in Australia it is referred to as the Burmilla Longhair. This has encouraged breeders to keep the breed type truer to the Burmilla standard and benefits the breed by using the larger gene pool ...
The British Shorthair played a large part in the American Shorthair's gene pool, however the American Shorthairs are now larger then their British cousin, with less rounded faces and longer legs and tails.
Over thirty years, hairless cats were bred with non-hairless cats, and the offspring were bred back to hairless cats, as breeders took care to preserve the hairless characteristic while ensuring a broad, diverse gene pool.
