Question

Chromosomes are classified based on the position of centromere. A chromosome having a terminal centromere is called

• A. Metacentric.
• B. Telocentric.
• C. Sub-metacentric.
• D. Acrocentric.

Answer 1

The correct option is B Telocentric.

Chromosomes are classified into four types based on the position of the centromere. These are metacentric, sub-metacentric, telocentric and acrocentric. A chromosome having centromere at the center is called as metacentric chromosome. In this, centromere divides chromosome into two equal arms. A chromosome having centromere slightly away from the center is called as sub-metacentric chromosome. A chromosome having centromere close to one of the end is called as acrocentric chromosome. A chromosome having a terminal centromere is called as telocentric chromosome.

Thus, the correct answer is option B.
