i think its d but don't rely on my answer because i'm not to great with science

agreene · Answer

since it is x linked and the mother is positive, both sons will have it because they will get their X from the mother (who has it) but they will get a Y from the father. Neither daughter will have it because they will get the X from the mother and X from the father, but since it is recessive they will just become carriers of it.

All of her sons would be infected........X*Y

The daughters would be heterozygous for it. X*X

X* = infected gene
X = normal gene

Its hemophilia is sex-linked recessive, then none of the daughters are infected. I think its this is the case.
