Match List I with List II regarding specific genotypes and their phenotypic expressions: List I List II A I^ A I^ B genotype in humans I Intermediate sized starch grains B Bb genotype in pea seeds II Small sized starch grains C I^ A i genotype in humans III Both A and B sugars on RBCs D bb genotype in pea seeds IV Only A sugar on RBCs Choose the correct answer from the options given below:

Step-by-step solution

The I^ A I^ B genotype in humans exhibits codominance, where both I^ A and I^ B alleles express themselves fully, resulting in the presence of both A and B sugars on the surface of red blood cells (RBCs). Thus, A matches with III. The Bb genotype in pea seeds shows incomplete dominance regarding starch grain size. The dominant allele B produces large starch grains, while the recessive allele b produces small starch grains. The heterozygous Bb genotype produces intermediate-sized starch grains. Thus, B matches with
