Tothepoint Hospital has a unique way of announcing the many births that occur there each day. Whereas most obstetricians happily proclaim, "It's a boy!" or "It's a girl!" to parents eager to receive such news, the doctors at Tothepoint instead issue a laconic, "XX. XY. XXY. XX." Assunta and Giacomo just delivered their first child, and the physician declared, "XY." What is the biological sex of Giacomo and Assunta's newborn?
