A telocentric chromosome differs from an acrocentric chromosome in that(a) The former have sub-terminal centrally located centromeres.(b) The centromere in the former is terminal and the latter has a medially located centromere.(c) The former has a subterminal centromere and the latter has a medially located centromere.(d) The former has a terminal and the latter has subterminal centromere.

The correct answer is (d) The former has a terminal and the latter has a subterminal centromere.

Telocentric and acrocentric chromosomes are two types of chromosomes based on the position of their centromeres.

A telocentric chromosome has a terminal centromere, which means the centromere is located at or near one end of the chromosome. This type of chromosome typically has a long arm and a very short or absent short arm.

On the other hand, an acrocentric chromosome has a subterminal or submedian centromere, which means the centromere is located closer to one end but not at the very end of the chromosome. This type of chromosome usually has a short arm (p-arm) and a long arm (q-arm).

Therefore, the correct statement is that a telocentric chromosome has a terminal centromere, while an acrocentric chromosome has a subterminal centromere.
