Polydactyly can be caused by multiple genetic factors, but it is often inherited as a dominant trait. This means that an individual only needs to inherit one copy of the gene in order to express the trait.
polydactyl is doninat in humans because it is an autosomal trait.
Yes, it's a dominant trait so if at least one of your parents had it you most likely will have it
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.

When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
Which form of gene pair is expressed when both dominant and recessive are present?
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
What is dominant recessive?
Dominant and recessive are terms used to describe how a particular allele (gene variant) is expressed in an individual's phenotype. A dominant allele will be expressed even if only one copy is present, while a recessive allele needs two copies to be expressed. Dominant traits mask the expression of recessive traits in an organism.
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
What is the different between dominant and recessive?
Dominant traits are expressed when an individual carries at least one copy of the dominant allele, while recessive traits are expressed only when an individual carries two copies of the recessive allele. Dominant alleles mask the expression of recessive alleles in heterozygous individuals.
Is polydactyly a recessive or domanant trait?
dominant
Is having five fingers or toes a recessive genetic trait?
Yes, because Polydactyly is a dominant allele.
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 can be dominant or recessive?
Alleles can be dominant or recessive
What is one genetic trait that masks another form of a trait?
Polydactyly is a genetic trait that can mask the presence of the recessive trait for normal digit number in humans. This means that individuals with polydactyly (extra fingers or toes) can carry the recessive allele for normal digit number without expressing it themselves.
The difference between a dominate and a recessive trait is?
A dominant trait is expressed when an individual has one or two copies of the dominant allele, while a recessive trait is only expressed when an individual has two copies of the recessive allele. Dominant traits mask the expression of recessive traits in heterozygous individuals.
Is melanoma dominant or recessive?
is malignant melanoma dominant or recessive
Can scans cause polydactyly?
No. Polydactyly is purely an autosomal dominant genetic disorder and cannot be caused by any environmental stress.
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
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.
How do you xxplain dominant and recessive?
Recessive
