Red-headedness is very recessive genetically. That this child has red hair means OP's wife is carrying red-headedness somewhere in her genetics. It's possible OP is as well, even if you'd have to go back a few generations to find it (which means OP might not even realize it's there). I'm very, very red headed. On my father's side you have to go back two generations to find a redhead, and on my mother's side you have to go back three.
OP, you will never know for sure whether this child is genetically yours unless you do a paternity test. Before you go down that road, you need to think through all of the consequences. Do you want to be your son's father? Right now it's presumed you are, and no one seems to be making a fuss about that. If it turns out you're not, what will that do to your relationship with your son? Will you disown him? Are you prepared for OM to step in and become his father, with visitation and everything? What if he is your genetic child, and he later finds out that you had a paternity test done on him? That could affect your relationship with him, if he feels you didn't love him enough to want to be his dad without the test, that somehow he's lesser in your mind.
