Abstract
The human Y chromosome is one of the smallest human chromosomes with an estimated average size of 50–60 Mb (Morton, 1991; Tilford et al., 2001). Size variability is mostly caused by polymorphism in the length of the constitutive heterochromatin located in the long arm in Yq12. It is characterized by its bipartite structure and function. It is flanked by pseudoautosomal regions at the distal short arm (PAR1) and distal long arm (PAR2), the sequences of which are shared by, and undergo meiotic recombination with the X chromosome. Between these two PARs there is the non-recombining region of the human Y chromosome (NRY), which comprises about 95% of the chromosome. This NRY does not undergo sexual recombination and is thus male-specific.
