Match List -I with list -II.

  List - I   List - II
(a) Metacentric chromosome (i) Centromere situated close to the end forming one extremely short and one very long arms
(b) Acrocentric chromosome (ii) Centromere at the terminal end
(c) Sub-metacentric (iii) Centromere in the middle forming two equal arms of chromosomes
(d) Telocentric chromosomes (iv) Centromere slightly away from the middle forming one shorter arm and one longer arm

Choose the correct answer from the options given below:

  1. (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)
  2. (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
  3. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
  4. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Solution

  List - I   List - II
(a) Metacentric chromosome (iii)

Centromere in the middle forming two equal arms of chromosomes. They appear like 'V' during anaphase.

(b) Acrocentric chromosome (i)

Centromere situated close to the end forming one extremely short and one very long arms. They appear like 'J' during anaphase.

(c) Sub-metacentric (iv) Centromere slightly away from the middle forming one shorter arm and one longer arm. They appear like 'V' during anaphase. 
(d) Telocentric chromosomes (iv) Centromere at the terminal end. They appear like 'I' during anaphase. The short arms is negligible in size.
