Question

Classify chromosomes based on the position of centromere.

Answer 1

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.
