Question

The female with this karyotype would have which genetic disorder? A. Klinefelter's syndrome B. Turner's syndrome C. trisomy-21 D. no disorder

Answer 1

The right answer is D.

This subject has a normal karyotype in terms of chromosome number.

In Kleinfelter's syndrome a karyotype with 2X and a Y (XXY) is observed, and the subject is male (there is no Y chromosome in the image).

In Turner syndrome, there is only one X chromosome (in this karyotype there are two).

In Trisomy 21 we observe three chromosomes 21 (in the picture there are two).
