Polydactylism, or having one or more extra fingers or toes, is probably the most common abnormality of development found at birth. Polydactylism is reported in about 2 per 1000 children. However, many of the simpler cases are taken care of in the nursery by the obstetrician or pediatrician and don't show up in these statistics.

Polydactyly and syndactyly can occur simultaneously when extra digits are fused
Polydactyly is more common in men, because it is a genetic disorder. Because females have 2 X chromosomes, a recessive trait passed down on one will be covered by the dominant trait on their other X chromosome for no polydactyly. Males though, have an X and Y chromosome which means that that the Y chromosome, carrying no trait for polydactyly, will not affect an X chromosome with the allele for polydactyly. Hence, polydactyly is found in men more than women.

Polydactyly can be diagnosed by external observation, x ray, and fetal sonogram
No. Polydactyly is purely an autosomal dominant genetic disorder and cannot be caused by any environmental stress.
