Question

which individual is shown in the karyotype?
male with turner syndrome
male with klinefelter syndrome
female with turner syndrome
female with klinefelter syndrome

Explanation:

1. First, analyze the sex chromosomes: The karyotype shows X and Y (XY) plus an extra X (so XXY), indicating male (since XY is male) and Klinefelter syndrome (which is XXY, extra X in males).
2. Turner syndrome is XO (missing a sex chromosome), so options with Turner are incorrect. Klinefelter in females is not possible as females are XX; Klinefelter is male (XXY). So the correct option is male with Klinefelter syndrome.

Answer:

B. male with Klinefelter syndrome
