  2. BA-III, B-IV, C-I, D-II
  3. CA-IV, B-I, C-II, D-III
  4. DA-I, B-II, C-III, D-IV

Correct answer

B. A-III, B-IV, C-I, D-II

Step-by-step solution

Down's syndrome is due to presence of an additional copy of chromosome number 21. Klinefelter's syndrome is caused due to presence of an additional copy of X-chromosome. -Thalassemia is controlled by two closely linked genes on chromosome 16 of each parent. -Thalassemia is controlled by a single gene HBB on chromosome 11 of each parent.
