Question

Give the typical sex-chromosome complement found in the cells of people with Turner syndrome, Klinefelter syndrome, and with the androgen-insensitivity syndrome. What is the sex-chromosome complement of triple-

�
X females?

Answer 1

Individuals with Turner syndrome typically have a sex-chromosome complement of 45,X, while those with Klinefelter syndrome exhibit 47,XXY. Androgen-insensitivity syndrome is associated with a 46,XY complement. Triple-X females, however, possess a sex-chromosome complement of 47,XXX.

Step-by-step explanation:

Turner syndrome results from the absence of one X chromosome, leading to a 45,X karyotype. In contrast, Klinefelter syndrome arises from the presence of an extra X chromosome, resulting in a 47,XXY chromosomal configuration. Androgen-insensitivity syndrome occurs when individuals with a 46,XY karyotype exhibit reduced responsiveness to androgens. Triple-X females, as the name suggests, carry an extra X chromosome, resulting in a 47,XXX chromosomal complement.
