According to the phenotypic diagnosis a female patient has been provisionally diagnosed with X-chromosome polysomia. This diagnosis can be confirmed by a cytogenetic method. What karyotype will allow to confirm the diagnosis?
- A. 47(XXX)
- B. 47(XXY)
- C. 46(XX)
- D. 48(XXYY)
- E. 48(XXXY)
Hint
Decide how many X chromosomes a woman with X-chromosome polysomy must carry and whether a Y chromosome may be present, then check the total chromosome number.
