One of the polydactyl cats at the Ernest Hemingway House in Key West, Florida.This particular cat has seven (two extra) toes on each paw. A polydactyl cat is a cat with a congenital physical anomaly called polydactyly (also known as polydactylism or hyperdactyly), which causes the cat to be born with more than the usual number of toes on one or more of its paws.
Munchkin or dwarf cat gene (dominant). Cats heterozygous for this gene (Mkmk) have shortened and thickened legs, because this gene causes dwarfism in cats. Cats with this mutation have lived naturally in feral populations worldwide. However, cats with this gene are also the basis for several intentionally selected breeds of dwarf cat.
Polydactyly also occurs in dogs, cats, and small mammals such as guinea pigs [78] and mice. [79] Cats normally have five digits on the front paws and four on the rear. Polydactyl cats have more, and this is a moderately common condition, especially in certain cat
Normally, cats have eighteen toes—five on each front paw and four on each back paw. However, the gene for polydactyly can cause a various number of toes to appear, from a simple extra thumb to ...
Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry, it can predict established traits ( phenotypes ) of the offspring of particular crosses. In medical genetics , cat models are occasionally used to discover the function of homologous human disease genes.
Maine Coon cats are known to have originated in Maine. However, their lineage is surrounded by mystery, folk tales, and myths. One myth claims the Maine Coon cat is a hybrid with another animal species, such as the raccoon or bobcat. The second myth states the cats are descendants of Viking ship's cats, known today as the Norwegian Forest cats.

These genes are linked to neural crest and central nervous system development. These genes affect embryogenesis and can confer tameness, smaller jaws, floppy ears, and diminished craniofacial development, which distinguish domesticated dogs from wolves and are considered to reflect domestication syndrome. The study concluded that during early ...
