Question

Quizplus · Accepted Answer

Turner's syndrome is characterized by the absence or abnormality of one of the X chromosomes in females. This results in short stature, infertility, and underdeveloped sexual characteristics, which are consistent with Sheila's symptoms. Option A (PKU) and option B (Down syndrome) are genetic disorders caused by chromosomal abnormalities that do not typically present with the same symptoms as Turner's syndrome. Option C (Klinefelter's syndrome) involves an extra X chromosome in males, which can result in infertility and other symptoms, but is not typically associated with short stature or underdeveloped sexual characteristics in females.
