A woman with a genetic disease marries a man who does not carry the disease. It is not possible for their children to carry the disease. The disease must be

a) sex - linked

b) recessive

c) dominant

d) cause by an extra chromosome

I think the answer is recessive, can someone please check to see if that's right? Thanks!

With all due respect, can someone please check my answer???
This is very difficult. Forgive me if i am wrong. So there is a chance that the children may/may not have the disease.
However, it is possible that the disease is NOT Dominant. Because if it was, then the children would have the disease. SO the answer is B if i am correct.
