Science of race mixing

My wife and I are going to have babies soon. She is Chinese and I am American, I estimate 87.5% British and 12.5% Native American (I did a DNA test and got 100% British so I guess I didn't get any of the major genotypes of Natives). However, I do have brown hair and brown eyes. We are both above average in IQ, I estimate around 120-130 IQ since we were top-of-our class engineers at a good school.

Scientifically, what can I expect? Is mental illness a serious concern? How about IQ? How will our traits mix? I won't get an abomination like pic related, right? I know there are plenty of successful hapas compared to mixed people of other races, but I see a lot of shitposting about AMWF on /pol/ and other boards.
