What is a common characteristic of Turner’s Syndrome?

• A. Increased height and sexual development
• B. Absence of an X chromosome
• C. Presence of two X chromosomes
• D. Advanced bone density

Answer: (B)

Turner’s Syndrome is characterized by the absence of all or part of one of the two X chromosomes in females, which is crucial for normal development and function. This chromosomal abnormality leads to a variety of physiological and developmental features associated with the syndrome. Individuals with Turner’s Syndrome typically exhibit short stature, delayed growth, and may have underdeveloped physical features associated with puberty due to the lack of sufficient estrogen production. The absence of the second X chromosome is a defining factor that contributes to the condition's key characteristics, such as, for some, heart defects, kidney problems, and learning difficulties, particularly in spatial understanding. The other options indicate features that are not characteristic of Turner’s Syndrome or misrepresent the genetic basis of the condition.
