b. 5-alpha reductase deficiency (5ARD)
c. Congenital adrenal hyperplasia (CAH)
d. Klinefelter syndrome
e. Turner syndrome

Answer 1

Turner syndrome, described by having only one X chromosome (XO genotype), is an intersex condition with distinct physical characteristics and usually results in sterility.

Step-by-step explanation:

Someone with a genetic variation resulting in having only one X chromosome describes an intersex condition known as Turner syndrome. Turner syndrome is characterized as having an XO genotype (i.e., only a single sex chromosome), and corresponds to a phenotypically female individual with specific physical features.

These features can include short stature, webbed skin in the neck region, as well as hearing and cardiac impairments. Individuals with Turner syndrome are typically sterile due to the absence of the second sex chromosome.
