The correct answer is: Turner Syndrome.

Explanation:

Turner syndrome is a genetic condition produced by a chromosomal abnormality in which one of the two X chromosomes, as they are commonly found in females, is missing.

Women with Turner syndrome are more likely short in height, have a short and webbed neck, and are infertile. Their gonads (ovaries) have not properly developed so their puberty will not be normal, though the appearance of secondary sexual characteristics such as breasts or hips can be promoted with Estrogen replacement therapy.
