Which sex-linked chromosomal disorder affects females and results in only 45 chromosomes?

Explanation:
Turner's syndrome is a sex chromosome monosomy. In this condition, a female has only one X chromosome (45,X) instead of the usual two sex chromosomes, giving a total of 45 chromosomes. Because one X chromosome is missing, the female phenotype arises, and common features include short stature and infertility, along with other developmental differences. Down syndrome is an autosomal trisomy (47 chromosomes) involving chromosome 21, not a sex chromosome issue. Klinefelter syndrome is 47, XXY and occurs in males. Triple X syndrome is 47, XXX and occurs in females.
