Codominant genes involves two dominant alleles that are expressed and create a new trait.
Explanation:
CO-dominant traits are both expressed in the phenotype of the organism that bears the alleles. An example is the dominant alleles of a trait for color. If both Red and White petal color alleles are dominant, a flower will exhibit striations of both Red and White color on its flower Petals. However, if the two traits show incomplete dominance, the two traits do not have complete dominance over the other so the flower petals will be pink (an intermediate between Red and White)
