Which of the following is NOT a type of chromosome, on the basis of the location of the centromere?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e Lophocentric.

Lophocentric is not a type of chromosome based on the location of the centromere. The four primary types of chromosomes based on the position of the centromere are:

  • Metacentric: Centromere is located in the middle, dividing the chromosome into two equal arms.
  • Submetacentric: Centromere is located closer to one end, resulting in one long arm and one short arm.
  • Acrocentric: Centromere is located very close to one end, producing one long arm and one extremely short arm.
  • Telocentric: Centromere is located at the very end of the chromosome, resulting in one long arm and no short arm.
