Turner syndrome is associated with absence of one X chromosome; what is the overall chromosomal count in these individuals?

Explanation:
Turner syndrome comes from monosomy X, so there is only one sex chromosome instead of a paired set. Humans normally have 46 chromosomes, and losing one chromosome reduces the total to 45. Therefore, individuals with Turner typically have 45 chromosomes (karyotype 45,X). In mosaic Turner, some cells may have 46, but the classic count associated with the condition is 45.
