Co-dominance occurs when there is no dominate or recessive gene. As a result, meither allele is masked in the offspring. An example of this is the alleles for feather color of chickens are codominant. Another example can be found in cattle. Red hair and white hair are codominant. Heterozygous cattle have coats with both white hairs and red hairs. From a distance, heterozygous cattle look pinkish brown, a color called roan. Hope this helps.
