Which of the following is an autosomal disorder______________?
Correct answer: A. Down's syndrome
- A. Down's syndrome
- B. Klinifelter's syndrome
- C. Turner's syndrome
- D. Jacob's syndrome
Explanation
Down syndrome is usually caused by trisomy 21, meaning there are three copies of autosomal chromosome 21. Klinefelter syndrome, Turner syndrome and Jacobs syndrome involve sex chromosomes, so they are sex-chromosome abnormalities. The common trap is Klinefelter syndrome, but its XXY chromosome arrangement is not autosomal.
