Mosaicism also occurs in men with Klinefelter's Syndrome.  This karyotype
consists of 47,XXY usually; but can have many Xs followed by a Y.  For
Klinefelter's Syndrome to be considered Mosaic two cell lines has to
exist.  For example: 46,XY/ 47,XXY.  Klinefelter's are sterile, however a
mosaic may have normal reproductive cells (46,XY) and thus be able to
reproduce even if the rest of his body possesses the 47,XXY cells.
