Sol.(c) [Key Concept: Codominance — F1 Resembles Both Parents] CO-DOMINANCE is depicted by a cross in which F1 resembles BOTH parents simultaneously. In codominance, both alleles are fully expressed in the heterozygote, so F1 shows characteristics of BOTH parental phenotypes at the same time. Example: ABO blood group — AB blood group individual shows both A and B antigens (both parental blood group characteristics). This differs from incomplete dominance where F1 has an INTERMEDIATE phenotype (not identical to either parent).
