Human blood has four phenotypes: A, B, AB, and O. The genes for A and B are dominant, while O is recessive. If a person has AB blood type, what inheritance pattern is demonstrated?(1 point)

Answer 1

The inheritance pattern demonstrated by a person with AB blood type is codominance. In codominance, both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that shows both traits equally, as seen in the AB blood type where both A and B alleles are expressed.
