Question

Quizplus · Accepted Answer

The combination of Iᴬ and Iᴮ alleles results in codominance, where both alleles are expressed equally and separately. This means that individuals with the Iᴬᴵᴮ genotype will have both A and B antigens on their red blood cells, rather than one dominating over the other. The other options either have a dominant allele (Iᴬ or Iᴮ) or have only one type of allele present (ii).
