NEW YORK (GenomeWeb) – A pair of studies appearing online today in Nature are uncovering evolutionary patterns for the mammalian Y chromosome and revealing conserved Y chromosome sequences stemming from ancestral, dosage-sensitive genes that have acquired functions outside of the male reproductive system, in some cases.

Although the Y chromosome is notorious for gene loss and erosion, the new research suggests that it has remained relatively stable in recent evolutionary history, following a series of early sequence jettisoning events.
