Question

Males are more often affected by s*x-linked traits than females because?

A) Males are hemizygous for the X chromosome

B) Female hormones such as estrogen often compensate for the effects of mutations on the X

C) Mutations on the Y chromosome often exacerbate the effects of X linked mutations

D) Male hormones such as testosterone often exacerbate the effects of mutations on the X chromosome

E) X chromosomes in males generally have more mutations than X chromosomes in females

Answer 1

(A) because males have an X chromosome and a Y chromosome. If X has the disease, Y wont be able to mask it because it is too small. However, if Y had the disease, X is able to mask it.

in females, there are two X chromosomes. so if one of the X has the disease, the other X is able to mask it to kill the disease.

this is why males are more often affected by s*x linked traits than females

hope i helped!!!
