My wife doesn't look like me. We have reasonably different ethnic backgrounds (common Scottish ancestry maybe 5 generations ago, maybe 5% ethnic commonality at best). We have an autistic child. So, what's your conclusion?
I bet you already knew this is what I meant and didn't actually need me to spell it out for you. As an aside, I read elsewhere that you and your wife are both from Western Europe. That's actually a lot closer than I had in mind; I said breed with someone who really doesn't look like you. :)
