1. A woman who is colorblind who also has a colorblind daughter is suing a normal vision man for paternity. You have been called into court as an expert in genetics to testify. What do you tell the jury?
2. A couple (both of which are normal) has a son that has Duchenne muscular dystrophy. This is a rare sex-linked recessive disorder which causes muscle deterioration that almost always affects boys. The parents believe that the hospital mixed their child up with a normal child and sue the hospital. You have once again been called as an expert in genetics to testify. What do you tell the jury? Is it possible that these are the biological parents or did the hospital make a mistake?
