telocentric chromosome

For example, the standard house mouse karyotype has only telocentric chromosomes.

A telocentric chromosome's centromere is located at the terminal end of the chromosome.

The X-chromosome is a large, and the Y-chromosome a small telocentric chromosome.

Humans do not possess telocentric chromosomes.

The karyotype of the house mouse normally consists of 40 telocentric chromosomes, but in certain regions in Europe, mice with karyotypes containing fewer than 40 chromosomes can be found.
