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 having five fingers or toes a recessive genetic trait?

Yes, because Polydactyly is a dominant allele.


Is polydactyly state recessive or dominant?

It is dominant but the frequency of the allele within any given population is very small so it only appears as though it is a recessive trait.


Can polydactyly be passed down by trait?

Yes, it's a dominant trait so if at least one of your parents had it you most likely will have it

Who is more likely to get polydactyly disease?

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.

No, an example disproving this is polydactyly (having more than five fingers) is a recessive trait.

What type of disease is polydactyly?

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).


What race has the most cases of polydactyly?

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.

Is dominant better then recessive?

Dominant does not necessarily mean better compared to recessive. For example, polydactyly, an autosomal dominant disorder, is when the person has 6 fingers on one or both hands. Another example would be achondroplasia, which is a genetic disorder where the cartilage of the body turns into bones.


A small founding population of a few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyly six fingers What is this an example of?

A+ Genetic drift The Founder Effect The founder effect is when a few individuals of a species form a new population. The gene pool composition, therefore, is not reflective of the gene pool of the original population. Think of this as a small number of people starting their own colony. This is an example of the Founder effect because Polydactyly is a dominant trait. And in a large population, it will be rare finding a person with a 6th digit. In a smaller population, however, polydactyly has a higher frequency of this allele, because the smaller the population, the higher the sensitivity for inbreeding and lower genetic variation. So, polydactyly (dominant allele) + Increase inbreeding= Higher polydactyly allele frequency.
