A telocentric chromosome is a type of chromosome where the centromere is located at or very near one end. In other words, the centromere is terminal, positioned at the extreme end of the chromosome. This configuration results in one long arm (q) and one very short arm (p).Telocentric chromosomes are relatively rare in most organisms, but they are more commonly observed in certain species, such as plants and insects. They are typically formed through a structural rearrangement, such as a centric fusion or centric fission event, where the centromere migrates to one end of a chromosome. |
