Text Solution
Verified by Experts(i) Metacentric chromosome ; (ii) Sub; (iii)Acrocentric chromosome ; (iv)Telocentric chromosome
Based on the position of the centromere, the chromosomes can be classified into four types.
(i) Metacentric chromosome - It has middle centromere forming two equal arms of the chromosome.
(ii) Sub-metacentric chromosome - It has centromere slightly away from the middle of the chromosome resulting into one shorter arm and one longer arm.
(iii)Acrocentric chromosome - In this, the centromere is situated close to its end forming one extremely short and one very long arm.
(iv)Telocentric chromosome - It has a terminal centromere.
