It is the phenomenon in which a gene for a trait exists in more than two allelic forms.
|
It is the phenomenon of the ability of a single gene to have more than one phenotypic effect.

2.
|
The alleles can show codominance. e.g. the gene for human blood groups exists in three allelic forms, $1^A$, $1^B$ and i.

Codominance is not exhibited. e.g. a single gene in garden pea controls seed shape and size of starch grains.
