A couple who have no children seek genetic counseling because the husband's two brothers died in their teens of duchenne's. Which of the following describes the husband's risk of being a carrier of DMD?
a) 0
b) 1/4
c) 1/3
d) 1/2
e) 3/4




duchenne muscular dystrophy is x linked recessive so he cant b a carrier if he got diseased allele from his mother he has disease if normal he is normal so choice A


agree with yasmeen


only female r carriers for x linked ds,the male has just one x ,normal or diseased


hahaha!! good one, yasmeen!

of couse, if he had DMD he would be already dead.. not married and in the mood of having kids! unless he married at 5! nod
