Considering that chromosome 13 is the largest acrocentric chromosome with the lowest gene density among all human chromosomes (17), its stability may differ from those of chromosomes 18 and 21.
Approximately 500 species of entelegyne spiders, representing nearly 30 families, have a diploid number varying between 2n = 14 and 2n = 52, a predominantly acrocentric chromosome morphology, and a SDCS of the [X.

Further subdivision of translocation types can be made according to the exchange of chromosomal material and are classified as: (i) reciprocal, when segments from two different chromosomes have been exchanged; or (ii) robertsonian, in five acrocentric chromosomes (13, 14, 15, 21 and 22), where long arms fuse to form a single chromosome with a single centromere.
