KROK 1 2017 – Question 113 · KROK (Medicine) · Biology
Clinical presentations of a woman allowed provisionally diagnosing her with X polysomy. Cytogenetic method is applied to clarify the diagnosis. The diagnosis will be confirmed if the patient’s karyotype is:
- A. 48, XXYY
- B. 48, XXXY
- C. 46, XX
- D. 47, XXX
- E. 47, XXY
Hint
Polysomy means one or more extra copies of a chromosome; consider what the sex chromosome complement of a woman must be, and how the total chromosome count then changes.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
