This deletion of the majority (~9/10) of the male-specific region of the long arm (MSYq) arose in a mouse carrying the 11 kb Srydl1Rob short arm deletion that removes Sry. The deleted region on the long arm included most or all copies of the Ssty gene family. The Rbmy gene family on the short arm and the pseudoautosomal region were left intact. (J:89616)
