Blood type is controlled by two equally dominant genes. What type of example is this?

recessive dominance
incomplete dominance
sex-linked genes
codominance

codominance

Explanation: Codominance is a heterozygous condition in which the two alleles that control a trait equally express themselves in the phenotype. In codominance, instead of one allele being dominant over the other, neither of them is completely dominant. In codominance, the two versions of a gene manifest equally phenotypically, this means that none of the alleles is able to mask the effect of the other.
