Answer:
XX females have one Barr body per cell, XXX females have 2 Barr bodies per cell, and XXY Klinefelter males have one Barr body per cell (Barr bodies are not observed in XY males). This is why X chromosome aneuploidy can be tolerated; all but one of the extra X chromosomes is unactivated.

Explanation:
Like females, XXY males with Klinefelter syndrome will convert one X to a Barr body in each cell. Triple X females (as well as Klinefelter males with more than two X chromosomes) neutralize their extra Xs by forming additional Barr bodies.
