People with klinefelter syndrome have a total of 47 chromosomes (47, xxy). Most men are born with a pair of xy chromosomes, while most females are born with pair of xx chromosomes Klinefelter syndrome occurs when a male is born with an extra x chromosome Thus a male with klinefelter has xxy instead of the usual xy pair. A male fetus typically ends up having an xxy chromosome due to either the ova or the sperm containing an extra x chromosome Statistically more probability of xxy syndrome is observed in male babies delivered by an older mother approaching menopause.
Most often, klinefelter syndrome is the result of one extra x (written as xxy) Occasionally, variations of the xxy chromosome count may occur, the most common being the xy/xxy mosaic. Normal females have two x chromosomes, and males have an x and a y
