Question:
In which type of chromosome, the centromere is located slightly away from the middle?
In which type of chromosome, the centromere is located slightly away from the middle?
Show Hint
Sub-metacentric chromosomes have a centromere slightly off-center, leading to arms of unequal length.

- Metacentric chromosome
- Sub-metacentric chromosome
- Acrocentric chromosome
- Telocentric chromosome

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Chromosomes are classified based on the position of the centromere:
- Metacentric Chromosome: The centromere is located at the center, dividing the chromosome into two equal arms.
- Sub-metacentric Chromosome: The centromere is slightly away from the middle, resulting in one arm being slightly longer than the other.
- Acrocentric Chromosome: The centromere is located close to one end, producing a very short arm and a long arm.
- Telocentric Chromosome: The centromere is at the very end, forming a single arm.
In sub-metacentric chromosomes, the arms are unequal due to the centromere being slightly off-center.
