Answer: 2. Klinefelter's syndrome

Key idea: Klinefelter's syndrome is XXY.

The individual is male with overall masculine development but also gynaecomastia (breast development), underdeveloped testes and sterility. Turner's syndrome (XO) is female and sterile; Edward syndrome is trisomy 18; Down's syndrome is trisomy 21.
