In the ABC model, the acquisition of floral organ identity is regulated by the floral homeotic genes namely A, B and C. A wild-type flower is depicted below. Consider the following mutants i. loss of gene C ii. loss of gene A iii. loss of gene B iv. loss of genes B and C Possible floral phenotypes (P-S) resulting from these mutations are given below. Based on this ABC model, the correct option(s) is(are)

Options

  1. A(i) corresponds to R and (iv) corresponds to Q .
  2. B(i) corresponds to S and (ii) corresponds to Q .
  3. C(ii) corresponds to P and (iii) corresponds to S .
  4. D(iii) corresponds to P and (iv) corresponds to R .

Correct answer

C. (ii) corresponds to P and (iii) corresponds to S .
