Question

Quizplus · Accepted Answer

Klinefelter syndrome is a sex-linked syndrome where males have an extra copy of the X chromosome. This results in males having XXY instead of the typical XY chromosome pairing. This can lead to developmental and hormonal imbalances, including infertility and reduced muscle mass. Choice A, Down syndrome, is not a sex-linked syndrome and is caused by an extra copy of chromosome 21. Choice B, Fragile X syndrome, is also not a sex-linked syndrome and is caused by a mutation on the X chromosome. Choice D, Turner syndrome, is a sex-linked syndrome but it occurs in females who are missing one X chromosome, not males with an extra X chromosome.
