Polydactyly is a genetic disorder which leads to one having six fingers or toes. This is also known as hexadactyly. It is caused by an autosomal dominant gene.
~
Poly = many
dactly = fingers and toes.
Polydactyly means more than the usual number of fingers and/or toes. Some cases can be genetic but most are not and there can be any number (not necessarily 6).

Who discovered polydactyly?
Tyler Steven Hayden discovered polydactyly.
If both parents are heterozygous for polydactyly what percentage of offspring will exhibit polydactyly?
75%
When does polydactyly occur?
Polydactyly and syndactyly can occur simultaneously when extra digits are fused
How is Polydactyly treated?
Polydactyly can be corrected by surgical removal of the extra digit or partial digit
What are polydactyly and syndactyly?
Polydactyly is the term for the presence of extra fingers. Syndactyly is the term for fused fingers.
Is polydactyly common in men or women?
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.
Is there a way to detect a carrier of polydactyly?
Polydactyly can be diagnosed by external observation, x ray, and fetal sonogram
Can scans cause polydactyly?
No. Polydactyly is purely an autosomal dominant genetic disorder and cannot be caused by any environmental stress.

How is polydactyly prevented?

What Type Of Mutation is Polydactyly?
Polydactyly is a mutation characterized by more than five digits on a hand or foot. Interestingly, it is a genetically dominant condition.
