Detailed explanation-1: -Explanation: Codominance means that more than one type of dominant allele for the same gene is present. If both black and white fur are dominant, then heterozygous (Aa) offspring would be spotted with black and white.
Detailed explanation-2: -Codominance. In people, one codominant trait that you can’t really observe by looking at a person, but many people know about themselves, is blood type. People with the AB blood type have one A allele and one B allele. Because both alleles are expressed at the same time, their blood type is AB.
Detailed explanation-3: -What is the difference between incomplete dominance and codominance? Codominance signifies that no allele can block or mask the expression of the other allele. Incomplete dominance signifies the condition in which a dominant allele does not completely mask the effects of a recessive allele.
Detailed explanation-4: -Examples of codominance in animals include speckled chickens, which have alleles for both black and white feathers, and roan cattle, which express alleles for both red hair and white hair. Codominance is also seen in plants.
