Male mammals have a single X and a Y chromosome. The Y chromosome is small, containing a lot of repeated sequences and few active genes, but carries a sex-determining factor, which determines maleness, as well as other male-specific functions such as steps in spermatogenesis. Molecular work suggests that the Y is best understood in terms of its evolutionary history.
