Correct answer: E. XXY
- A. XX
- B. XXX
- C. XO
- D. XYY
- E. XXY
Explanation
Klinefelter's Syndrome is characterized by having an extra X chromosome, resulting in a karyotype of XXY. Here are explanations for each of the options:1. XX: A karyotype of XX is typical for females.2. XXX: A karyotype of XXX is a condition known as Triple X Syndrome, where females have an extra X chromosome. It is a separate condition from Klinefelter's Syndrome.3. XO: A karyotype of XO represents Turner Syndrome, where individuals have only one X chromosome and no second sex chromosome. This is different from Klinefelter's Syndrome.4. XYY: A karyotype of XYY represents a condition known as Jacob Syndrome. It involves an extra Y chromosome, which is different from Klinefelter's Syndrome.5. XXY: Klinefelter's Syndrome is characterized by having an extra X chromosome, resulting in a karyotype of XXY. Individuals with Klinefelter's Syndrome typically have male characteristics but may exhibit various physical and developmental differences due to the extra X chromosome.So, the correct answer is XXY for Klinefelter's Syndrome.
