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

• A. (a)- (iii); (b) - (i); (c) - (iv);(d) - (ii)
• B. (a)- (i); (b) - (iii); (c) - (ii);(d) - (iv)

Answer 1

Answer: (A)

(a)- (iii); (b) - (i); (c) - (iv);(d) - (ii)

Answer 2

The metacentric chromosome has a middle centromere forming two equal arms of the chromosome.
- In the case of an acrocentric chromosome the centromere is situated close to its end forming one extremely short and one very long arm.
-The sub-metacentric chromosome has centromere slightly away from the middle of the chromosome resulting in one shorter arm and one longer arm.
-Telocentric chromosomes have a terminal centromere.
