A question about Genes&society!!!
I don't know the answer is C. Who can tell me? If it is recessive, the mother should be a carrier. But it said that she is perfectly free of the disease.
Thanks a lot!!! (more...)
"perfectly free" here means no symptom.
the carrier is perfect free of the *disease*.
so it should be Sex(X)-linked, recessive.
