Polydactyly

Polydactyly, or polydactylism, is the anatomical abnormality of having more than the usual number of digits on the hands or feet. It is a congenital abnormality, usually genetically inherited as an autosomal dominant trait[1]surgically[1], although the frequency varies greatly from population to population. It is higher in some groups (e.g. the Pennsylvania Dutch in the United States) due to the founder effect[1].

Historically, polydactyly has in some areas been considered an indication of witchcraft.

Types of polydactyly

There are several types of polydactyly, of varying frequency. Here are some of them:-

Marilyn Monroe's alleged polydactyly

A story that Marilyn Monroe was born with six toes resulted from the publication of photographs taken by the photographer Joseph Jasgur in March 1946. The pictures were published in the book The Birth of Marilyn: The Lost Photographs of Norma Jeane (1991) by Jasgur and Jeannie Sakol. Two of the pictures can be interpreted as showing six toes, although they can also be explained as tricks of the light. Since there is no corroborating evidence from other photographs or written records, the story is commonly dismissed as an urban legend (See Snopes and see [1] for photographic proof that her feet were normal).

Polydactyly in cats

Cats usually have four digits on the hind paws, and five on the front ones. Polydactyl cats usually have only one or two extra toes on each front paw, but can have as many as double the usual number, giving the appearance of having "double paws"[1].
