If a person has AB blood type, the inheritance pattern demonstrated is codominance. In codominance, both alleles (in this case, A and B) are expressed equally in the phenotype, resulting in the AB blood type.
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)

In this scenario, a tall pea plant (which can be either homozygous tall, TT, or heterozygous tall, Tt) is crossed with a short pea plant (which must be homozygous recessive, tt). Given that half the offspring are tall and half are short, it indicates that the tall parent must be heterozygous (Tt) crossing with the short parent (tt).
The allele that represents tallness would simply be designated as T. It represents the dominant allele for tallness.
