[Ms.RN]

Can someone please explain what x-linked recessive disease is? If mother is a carrier, why cant' daughters inherit this disease?

P.S. I hate OB!!! hate it, hate it, hate it!!!!

remember, females have two X chromosomes....the X without the faulty gene, over rides the one that does...that makes it recessive....dominant is when the faulty gene overrides the non faulty.....

Here is an explanation for you from an online Biology textbook of X-linkage and how it works:

Here is an advanced genetics wizard that will calculate the genetic makeup of offspring. Offers no educational explanation, but is interesting to use:
