They are typed as telocentric acrocentric

I thought they were acrocentric (centromere positioned so close to the end of the chromosome that the short arm of the chromosome is not visible) rather than telocentric (centromere located completely at the terminal end of the chromosome).

4 basic types of chromosomes , metacentric , submetacentric , acrocentric and telocentric .

A metacentric chromosome has two equal arms because the centromere can be found in the median position. A telecontric chromosome, on the other hand, is like a straight rod. Its centromere is in the terminal position.

Metacemtric is chromosomes where the arms are equal. Submetricus is when the chromosome arms are unequal.A telocentric chromosomes are chromosomes centromere is located at the terminal end of the chromosome.Telomeres may extend from both ends of the chromosome.
