Which genetic disorder is caused by monosomy of the X sex chromosome in females, leading to sterile individuals with short stature?

A. Down syndrome
B. Klinefelter syndrome
C. Turner syndrome✓ Correct Answer
D. Cri-du-chat syndrome

💡 Solution & Explanation

Turner syndrome is a chromosomal condition arising from monosomy of the X chromosome, leaving affected females with forty-five chromosomes instead of forty-six, which results in short stature and gonadal dysgenesis. Conditions like Down syndrome involve trisomy of chromosome twenty-one, whereas Klinefelter syndrome is characterized by an extra X chromosome in males. Chromosomal abnormalities of this type are routinely detected using karyotyping during medical screenings.
