Question

This syndrome that affects females is a consequence of having one X chromosome and no other sex chromosomes (XO). What is this called?

a) Klinefelter Syndrome
b) Turner Syndrome
c) Down Syndrome
d) Edwards Syndrome

Answer 1

Turner Syndrome is the condition in females caused by the presence of only one X chromosome (XO genotype) leading to sterility and physical abnormalities such as short stature and webbed neck.

Step-by-step explanation:

The syndrome that affects females, which is a consequence of having one X chromosome and no other sex chromosomes (known as an XO genotype), is called Turner Syndrome. In this condition, the affected child is always female, and women with Turner Syndrome are sterile because their sexual organs do not mature.

They often have a short stature, webbed skin in the neck region, hearing and cardiac impairments. Unlike Klinefelter Syndrome, which is characterized by an XXY genotype and affects males, Turner Syndrome is the result of monosomy, where there is a total absence of the second sex chromosome.
