Sexdactyly

From Wikipedia, the free encyclopedia

Sexdactyly is a genetic condition in which a person has six fingers on one or both hands, or six toes on one or both feet. This is a genetically inheritable condition; some populations feature a larger proportion of six-fingered people.

Sexadactyly, or hexadactyly, is not merely defined as having six finger per hand or six toes per foot. It requires that each of the six fingers have its own ray, so that no two fingers would be more "merged" than on a normal hand on X-rays (as in most forms of polydactyly). Nonspecialists and the media however use the terms interchangeably.

The biblical giant Goliath is said to have had six fingers on each hand and six toes on each foot.^{[citation needed]}
