Q: What is the correct answer for CUET UG Biology / Genetics Q49?

The correct answer is b. Let's match the blood group phenotypes (List-I) with their corresponding genotypes (List-II): (A) **Blood group A** phenotype is expressed by individuals with either two I^A alleles (homozygous I^A I^A) or one I^A allele and one recessive 'i' allele (heterozygous I^A i). So, (A)-(II). (B) **Blood group B** phenotype is expressed by individuals with either two I^B alleles (homozygous I^B I^B) or on

Let's match the blood group phenotypes (List-I) with their corresponding genotypes (List-II):
(A) **Blood group A** phenotype is expressed by individuals with either two I^A alleles (homozygous I^A I^A) or one I^A allele and one recessive 'i' allele (heterozygous I^A i). So, (A)-(II).
(B) **Blood group B** phenotype is expressed by individuals with either two I^B alleles (homozygous I^B I^B) or one I^B allele and one recessive 'i' allele (heterozygous I^B i). So, (B)-(I).
(C) **Blood group O** phenotype is expressed only when an individual inherits two recessive 'i' alleles (homozygous ii), as neither A nor B antigens are produced. So, (C)-(IV).
(D) **Blood group AB** phenotype is expressed when an individual inherits both an I^A allele and an I^B allele (heterozygous I^A I^B). Due to co-dominance, both A and B antigens are present. So, (D)-(III).
Combining these matches, we get: (A)-(II), (B)-(I), (C)-(IV), (D)-(III), which corresponds to option (b).
