Is Codominance Polygenic? | Contextresponse. Com
Codominance Is a Completely Different Concept. It Applies to Alleles of a Single Gene and Their Effect on a Phenotype. Polygenic Inheritance Is When a Trait...
.
In this way, what does polygenic mean in genetics?
A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic.
Also Know, is polygenic inheritance the same as incomplete dominance? In polygenic inheritance, the genes contributing to a trait have equal influence and the alleles for the gene have an additive effect. In incomplete dominance, one allele does not completely dominate or mask another. The phenotype is a mixture of the phenotypes inherited from the parent alleles.
Similarly, it is asked, what is a codominant trait?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
Is skin color a polygenic trait?
Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. Skin color is also a polygenic trait, as are hair and eye color.
