What type is a type of Gene where both allies can be expressed which statement best explains a person with AB blood type

Codominance

Explanation:

This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=i

IAIb = AB blood type

IbIb = B blood type

Iai = A

IaIa = A bloody type

Ibi = B blood type

ii = O blood type
