XYY syndrome. XYY syndrome is a genetic condition in which a male has an extra Y chromosome. There are usually few symptoms. These may include being taller than average, acne, and an increased risk of learning problems. The person is generally otherwise normal, including normal fertility.Click to see full answer. Considering this, what is XYY syndrome?XYY syndrome is a genetic condition that occurs when a male has an extra copy of the Y chromosome in each of their cells (XYY). Sometimes, this mutation is only present in some cells.Secondly, can females have XYY syndrome? Most cases of XYY syndrome are not inherited, and the syndrome occurs randomly in pregnancies of women from all ages and ethnic backgrounds. People normally have 46 chromosomes in each cell. Beside this, what gender is an XXY chromosome? A person’s gender is determined by the sex chromosomes: females have two X chromosomes, or XX; most males have one X chromosome and one Y chromosome, or XY. Males with XXY syndrome are born with cells that have an extra X chromosome, or XXY.Are XYY males infertile?Many men with 47,XYY karyotype are fertile in spite of their sex chromosome abnormalities. Some researchers have suggested that the extra Y chromosome is lost before meiosis,3,6–8 thus conserving fertility in these patients.
