What is XYY syndrome?

XYY syndrome is a chromosomal condition in which males have an extra Y chromosome. Males with this condition experience normal sexual development, however, there may be an increased risk of developmental delays in speech, language, motor, or behavioral abilities. The characteristics will vary widely.
