Isolating a strain to keep its genotype pure means it will inevitably become inbred.There needs to be a sensible balance.
Only cats The separation of the new colours of Siamese and Persians is considered artificial since the cats' conformation is unchanged.As mentioned earlier, pro-genotype cat fanciers lose sight of the fact that they are registering.One danger, pointed out by pro-genotype breeders is that accepting "lookalike" cats into a breed with a known genotype can introduce unwelcome unknown genes which could become widespread and result in undesirable traits later on. In some registries, Exotic Longhairs are identical to Persians, but may not be bred with Persians. Breeding to an unrelated line of the same breed (where possible) or outcrossing to another breed (where permissible) can ensure vigour. In sheep, centuries of selective breeding to improve the quality of wool has caused an important trait to be lost. A COI of 0 = no inbreeding; a COI of 0.25 = 25% inbreeding (typically brother-sister) and a COI of 0.01 = 1% inbreeding. Early Turkish Vans were reported to be temperamental, a problem apparently rectified by the importation of new stock.
Likewise, some registries do not allow chocolate or lilac Persians to be classed as Persians because the colours were introduced from Siamese cats (via the Himalayan breed) umpteen generations ago and are therefore "tainted". Although the head defect was present before Good Fortune Attempts to change the appearance of Burmese cats in America to produce a cat with a rounder head resulted in cats with congenital problems. This allows them to look at the effect of inbreeding in wild populaitons, something previously difficult or impossible as it was not possible to trace pedigrees. Enthusiasts preserve minority breeds because their genes may prove useful to farmers in the future, but at the same time the low numbers of the breed involved means that it runs the risk of becoming unhealthily inbred. However, cheetahs are already so highly inbred that individuals are already almost genetically identical so the impact of clones on the population will be to increase numbers rather than further decease genetic variation. Inbreeding depression is known to affect the immune system. American Burmese is is prohibited from competion in Europe and American
They can experience dwarfism.So many cats must be bred to produce the one money-maker the breeder’s looking to showcase. The loss of a large proportion of cats to one disease (e.g. Breeds in their infancy may need to pursue phenotypic breeding programs until the gene pool is wide enough to support breeding along genotypic lines. According to one theory, immunodeficiency may be caused by a simple lack of heterozygosity in the genes that control the immune system.

".Zoos engaged in captive breeding programs are aware of this need to outcross their own stock to animals from other collections. The "degree of microsatellite homozygosity" (what Amos calls "internal relatedness") means the number of identical markers. Selecting suitable outcrosses can reintroduce healthy genes, which might otherwise be lost, without adversely affecting type.Unfortunately, the "Burmese head fault", a lethal deformity that requires euthanasia, came hand-in-hand with the "Contemporary" look. and preferably not closely related to each other. The Sokoke is a recent breed being developed from a small pool of distinctive looking cats found in the Sokoke forest region of Kenya. Mankind has contributed to the loss of diversity by sport-hunting cheetahs and reducing the number of available mates.

'.There are health problems now associated with most breeds. It is the pairing of animals which are more closely related than the average population.
For breeders, it is a useful way of fixing traits in a breed - the pedigrees of some exhibition cats show that many of their forebears are closely related. Phenotype means "what it looks like" while genotype means "its genetic make-up". to increase meat yield), but to reintroduce it from primitive sheep would reduce other qualities selectively bred for over centuries.Most laboratory mice are becoming so highly inbred that they would probably not survive outside of a sterile laboratory due to poor immune systems (they are generally killed before this becomes a problem in the laboratory situation) and some strains become extinct due to reproductive failure. He defined "inbred" as matings between first cousins or closer.
