It's really a total gamble!
Darker features are supposed to be dominant, but it doesn't really mean much. Some kids look just like one parent, others like a mix, it's all up in the air
My son is half white (British/Irish) and then whatever I am (Italian & Mexican). He got my dark eyes, his father's chin/ears and hair...well, I guess we'll see when he grows any lol
Everyone says he looks like a male version of me, but today at a dr. appointment a little boy whispered (very loudly, ha) to his mom "How come her baby is white and she's not?" LOL!!!
His mom replied "He probably got it from his Daddy, just like you!"
Haha.
Anyway, it's fun to guess, but no matter what you get you will be surprised, I think. When my son was born DH and I both thought "WHO THE HECK IS THAT?!" All the imagining didn't prepare us at all!
