X-Linked Genes are Expressed

Question

X-linked genes are expressed
A) more often in males.
B) more often in females.
C) at equal rates in the two genders.

Accepted Answer

X-linked genes are found on the X chromosome, and males only have one X chromosome while females have two. Therefore, X-linked genes are expressed more often in males because they do not have a second copy of the gene to mask any possible traits or mutations.
