Chromosome Classification Based on the Position of Centromere

Q. A telocentric chromosome of metaphase consists of:

1. One centromere, one arm, and two chromatids
2. One centromere, two arms, and two chromatids
3. One centromere, one arm, and one chromatid
4. One centromere, two arms, and one chromatid

Q. When the centromere is situated in the middle of two equal arms of chromosomes, the chromosome is referred as :

1. Metacentric
2. Telocentric
3. Sub-metacentric
4. Acrocentric

Q. Identify the correct match between the type of chromosomes and the position of the centromere.

$\begin{array}{cc}\text{Chromosomes}& \text{Position of centromere}\\ \text{(A) Metacentric}& \text{(1) At the tip}\\ \text{(B) Telocentric}& \text{(2) Almost near the tip}\\ \text{(C) Acrocentric}& \text{(3) At the middle}\\ \text{(D) Submetacentric}& \text{(4) Slightly away from the middle}\end{array}$

1. (A)-(1), (B)-(2), (C)-(3), (D)-(4)
2. (A)-(2), (B)-(4), (C)-(3), (D)-(1)
3. (A)-(3), (B)-(1), (C)-(2), (D)-(4)
4. (A)-(3), (B)-(2), (C)-(1), (D)-(4)
