Detailed explanation-1: -Codominance Definition Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed. As a result, the phenotype of the offspring is a combination of the phenotype of the parents. Thus, the trait is neither dominant nor recessive.
Detailed explanation-2: -Correct answer: Codominance means that more than one type of dominant allele for the same gene is present.
Detailed explanation-3: –In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.
Detailed explanation-4: -Incomplete dominance occurs because neither of the two alleles is completely dominant over the other. This results in a phenotype that is a combination of both.
