XXY syndrome, also known as Klinefelter syndrome, usually occurs randomly and is not typically inherited. It is caused by an extra X chromosome and occurs in about 1 in 500-1,000 male births. While it can occur in other males within a family, it is generally due to chance rather than a hereditary pattern.
