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

Column I: (a) Dominance; (b) Codominance; (c) Pleiotropy; (d) Polygenic inheritance

Column II: (i) Many genes govern a single character; (ii) In a heterozygous organism only one allele expresses itself; (iii) In a heterozygous organism both alleles express themselves fully; (iv) A single gene influences many characters

Code :

(a) (b) (c) (d)

1. (ii) (i) (iv) (iii)

2. (ii) (iii) (iv) (i)

3. (iv) (i) (ii) (iii)

4. (iv) (iii) (i) (ii)

Best answer

Answer: 2. (ii) (iii) (iv) (i)

Key idea: Match each term with its meaning.

  • Dominance: in a heterozygote only one allele expresses: (ii)
  • Codominance: both alleles express fully: (iii)
  • Pleiotropy: one gene affects many characters: (iv)
  • Polygenic inheritance: many genes govern one character: (i)

So a-ii, b-iii, c-iv, d-i, which is option (2).
