Xyy redirects here. For the CIE XyY colour model, see XyY. XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births.or the CIE XyY colour model, see XyY.

XYY Syndrome is a genetic condition that occurs when a maleâs genes have an extra Y chromosome. Females typically have two X chromosomes (XX). Males typically have one X chromosome and one Y chromosome (XY).Males with this genetic condition have an extra copy of the Y chromosome in each of their cells (XYY).Most people have 46 chromosomes in each cell. Males with XYY syndrome have 47 because of the extra copy of the Y chromosome.However, sometimes this mutation is only present in some cells.ales with this genetic condition have an extra copy of the Y chromosome in each of their cells (XYY). Most people have 46 chromosomes in each cell. Males with XYY syndrome have 47 because of the extra copy of the Y chromosome.
