My Sister-in-law tried this out and it looked fun so I did all my kids. This is what I got:
Oaklee 3% more like Roger
Chance Equal 50% like Dad 50% like Mom.
Aubree looks 3% more like Roger
Caib Equal 50/50
Braden a whopping 20% more like his Mom.
So there you go. I'd have never guessed the results but it was fun.
