Turner's syndrome karyotype is typically

Explanation:
Turner syndrome is caused by the loss of one sex chromosome, so individuals are female but have only one X. This leads to a 45,X karyotype, often written XO. With just a single X, the genes that would normally come from a second sex chromosome are missing, producing the characteristic features of Turner syndrome while most autosomes are normal. Other sex chromosome patterns like XX, XY, or XXX correspond to different conditions, not Turner syndrome.
