I am mixed race asian/white. My husband is darker, olive toned caucasian.
One of our kids looks just like my husband.
Another slightly resemble me. Definitely looks about 1/5 asian
Another came out and if I hadn't seen it happen I would have been worried the kid was switched in the NICU. White, white skin. Golden blonde hair. Greenish blue eyes. Not a single asian feature on him. Looked nothing like either of us until about age six, when he suddenly started to favor photos of my husband as a child. Until then, he looked like he belonged to a different family.
Genes are a very strange thing.
