Turner syndrome is associated with which karyotype?

Explanation:
Turner syndrome results from monosomy X, so individuals have only one X chromosome. The classic karyotype is 45,XO, meaning 45 chromosomes with a single X. This distinguishes Turner from a normal female (46,XX), a typical male (46,XY), or triple X (47,XXX). Some patients can have mosaic patterns like 45,X/46,XX, but monosomy X is the hallmark association.
