well, yes. I read it on wikipedia.
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 is associated with different mutations and is a congenital phyiscal anomoly found in humans, dogs and cats. causing them to develop too many fingers or toes.
http://www.emedicine.com/derm/topic692.htm Postaxial hand polydactyly is a common isolated disorder in African black and African American children, and autosomal dominant transmission is suspected. Postaxial polydactyly is approximately 10 times more frequent in blacks than in whites and is more frequent in male children. In contrast, postaxial polydactyly seen in white children is usually syndromic and associated with an autosomal recessive transmission.
Polydactyly. JT
Polydactyly is a type of genetic mutation that results in individuals being born with extra fingers or toes. It is usually an inherited trait, although it can also occur spontaneously. Polydactyly is considered a rare condition.
Polydactyly has likely been known since ancient times, as references to extra fingers or toes can be found in historical texts and artwork. However, it was officially recognized and described in medical literature in the 18th century by various physicians and anatomists.
Customary law is based on customs and traditions of a particular community, often passed down orally, whereas common law is based on judicial decisions and precedent established by courts. Customary law is specific to a particular community, while common law is more standardized and applies broadly within a jurisdiction.
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).
A cat that has more than the usual number of toes is known as a polydactyl cat. Polydactyly is a genetic trait that causes cats to be born with extra toes, typically on their front paws. This condition is relatively common and can sometimes be seen in various cat breeds.
Polydactylys definition is the condition where a subject retains more than the normal amount of digits. In this case, digits can mean fingers. A child that is polydactyly has more than five fingers of each hand. It is possible for them to have six or more digits. This applies also to having more digits on your toes.
polydactyly is the condition of having more than the normal number of fingers &/ toes. i suppose this could effect person's self-image. but polydactyly does not, in & of itself cause mental illness.
IN the case of a HUMAN community, more money earned and higher quality of life the higher the survival rates for the occupants of that particular community.
