Human beings have cells with 46 chromosomes --2 sex chromosomes and 22 pairs of autosomal (non-sex) chromosomes. Males Klinefelter syndrome results in males who have at least one extra X chromosome. Usually, this occurs as a result of one extra X (written as XXY).are "46, XY" and females are "46, XX". These chromosomes are made up of extremely long DNA molecules in combination with chromosomal proteins.Two of these chromosomes, the sex chromosomes, determine if you become a boy or a girl. Females normally have two of the same sex chromosomes, written as XX. Males normally have an X and a Y chromosome (written as XY).
