Question

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

Answer 1

Answer:

codominance

Explanation:

Codominance is seen in inheritance of the ABO blood group alleles. Such alleles occupy the same locus on homologous chromosome. As such, only two can be found in an individual. Allele A causes the production of antigen a on the red blood cell membranes. Allele B produces antigen b. Allele O does not produce any antigen.

Alleles A and B are codominant each other being expressed equally in the phenotype. Because only two alleles can be found in an individual, there are six possible combinations and four blood groups in the ABO blood system because A and B are codominant but dominant to O.

Answer 2

Answer:

If both alleles are dominant, it is called codominance?. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A and B dominant alleles.
