What chromosome condition is Turner syndrome associated with?

Turner syndrome is indeed associated with the chromosome condition of having a missing one X chromosome, denoted as XO. This condition specifically affects females, who typically have two X chromosomes (XX). In Turner syndrome, the individual has only one X chromosome and lacks the second chromosome, which leads to various developmental and physical features associated with the disorder.

The absence of the second X chromosome can result in symptoms such as short stature, delayed puberty, infertility, heart defects, and distinctive physical features. Understanding this genetic makeup is crucial to recognizing how chromosomal abnormalities contribute to various syndromes and conditions.

Other options like XXY, XY, and XXX represent different chromosomal configurations that are associated with conditions such as Klinefelter syndrome and Triple X syndrome, respectively, but they do not pertain to Turner syndrome. Hence, the correct association of Turner syndrome with the XO (missing one X chromosome) configuration is a fundamental genetic fact.
