A 16-year-old adolescent is seen in your clinic. On physical examination, you note that he has small testis for his stated age and has poorly developed secondary sexual characteristics. In addition, on physical examination, there is notable gynaecomastia. He is rather tall, with abnormally long upper and lower limbs. A buccal smear is obtained and examined microscopically. How many chromatin positive inclusion bodies are seen?

(a) 0
(b) 1
(c) 2
(d) 3

In humans with more than one X chromosome, the number of Barr bodies visible at interphase is always one fewer than the total number of X chromosomes. For example, men with Klinefelter syndrome (47,XXY karyotype) have a single Barr body, whereas women with a 47,XXX karyotype have two Barr bodies.
