Inheritance pattern of polydactylism?
Polydactylism, or having extra fingers or toes, can be inherited in an autosomal dominant manner. This means that a child only needs to inherit one copy of the gene from one parent to express the trait. Offspring of a parent with polydactylism have a 50% chance of also having the condition.
Why doesn't polydactylism occur in everyone if it is a dominant trait?
Just because an allele is dominant does not mean that it is necessarily common.How common a version of a gene is (i.e. its frequency in a population) depends on how it affects an organism's chance of surviving to reproduce. Natural selection may favor a recessive allele of one gene and a dominant allele of another.
Is six fingers a dominate trait?
Having six fingers is typically considered a polydactyly trait, which is a rare genetic variation. Whether a trait is dominant or recessive depends on the specific genetic mutation causing it. In polydactyly cases, the inheritance pattern can vary, with some being dominant and others being recessive.
What does The disproportionately high appearance of polydactylism among the Amish suggests?

Who in the old testament of the Bible was mentioned and you found out they had suffered from polydactylism?

What is like to have polydatylism?
Polydactylism is a condition where a person is born with extra fingers or toes. It can sometimes be purely cosmetic and have no impact on a person's daily life, while in other cases it may require medical intervention to address any functional or aesthetic concerns. People with polydactylism may experience social stigma or curiosity from others due to their unique physical characteristics.
What is it called when a person has extra finger or toes?
Polydactyly means extra fingers or toes.Polydactylism
What accounts for the fact that polydactylism is prevalent and Tay-Sachs disease virtually absent in one human population inthe US while Tay-Sachs disease is prevalent and polydactylism vir?
Polydactylism is often prevalent in certain populations due to specific genetic traits that are passed down through generations, particularly in communities with a high degree of inbreeding, such as some Amish and certain African populations. In contrast, Tay-Sachs disease is more common in Ashkenazi Jewish populations due to a higher carrier rate of the recessive gene responsible for the condition, while polydactylism is less common due to different genetic factors. The differing prevalence of these traits within populations is a result of historical genetics, founder effects, and social factors influencing mating patterns.
What are some features of polydactyl?
Polydactylism is the presence of extra fingers or toes. It is caused by genetic mutations, typically inherited from the parents. Often the extra digit can be surgically removed. Polydactylism sometimes occurs alone, but more often with other abnormalities, such as cleft lip or palate, dental or vertebral deformities, and psychomotor retardation. Some of these can be corrected as well, so if your child is suffering from polydactylism they should be checked for other problems.
What do you call a person with more than five fingers?
The individual is a "polydactyl ". The condition is "polydactyly" or "polydactylism", a congenital anomaly. The extra digits are referred to as "supernumerary digits".

How do you treat polydactylism in horses?
Polydactylism (having more than the average number of toes), is fairly uncommon in horses and comes in two basic forms. Teratological form is where the limb is extensively deformed and the horse will typically be put to sleep. The atavistic form is more treatable and requires 'cosmetic' surgery. The excess toes will be amputated and the skin closed over the leg, usually the outcome for this type of surgery is good.
