Question

Match the terms in Column-I with their description in Column-II and choose the correct option.

• A. a-(ii), b-(iii), c-(iv), d-(i)
• B. a-(iv), b-(i), c-(iii), d-(ii)
• C. a-(iv), b-(iii), c-(i), d-(ii)
• D. a-(ii), b-(i), c-(iv), d-(iii)

Hint:

Codominance and dominance differ in allele expression: codominance shows both alleles, while dominance shows only one.

Answer 1

The Correct Option is A

Dominance occurs when one allele masks the other in a heterozygote (a-ii). Codominance is when both alleles are expressed fully in a heterozygote (b-iii). Pleiotropy refers to one gene affecting multiple traits (c-iv). Polygenic inheritance involves multiple genes influencing a single trait (d-i).
