Match the terms in Column-I with their description in Column-II and choose the correct option: Column - I Column - II (a) Dominance (i) Many genes govern a single character (b) Codominance (ii) In a heterozygous organism, only one allele expresses itself (c) Pleiotropy (iii) In a heterozygous organism, both alleles express themselves fully (d) Polygenic inheritance (iv) A single gene influences many characters

Options

  1. Aa - ii; b - i; c - iv; d - iii
  2. Ba - ii; b - iii; c - iv; d - i
  3. Ca - iv; b - i; c - ii; d - iii
  4. Da - iv; b - iii; c - i; d - ii

Correct answer

B. a - ii; b - iii; c - iv; d - i

Step-by-step solution

Dominance- In a heterozygous organism, only one allele expresses itself. Codominance- In a heterozygous organism, both alleles express themselves equally. Pleiotropy- A single gene influences many characters. Polygenic Inheritance- Many genes govern a single character.
