The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
Eye Colour
No, often many other alleles will also determine the same trait. For example, many alleles put together will determine a person's skin color.
The best example possible; blood types!
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.
A trait controlled by four alleles is said to have multiple alleles.
multiple alleles
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
eye color, blood type, hair color
Alleles are the same trait
