Biracial Children

My situation is regarding biracial children. I am white and my boyfriend is biracial (black mom, biracial dad (b&w)). We have a daughter together, she has very slightly tan skin, dark hair, brown eyes. His nephews, the same… He also has a son from a previous relationship. Mother is also white. We have had to fight her (through the courts) for visitation. A DNA test is going to be done this week. His son has pale white skin, thin blonde hair, blue eyes. I know it’s possible, genetics are crazy and unpredictable! Their relationship ended due to her cheating at the end of her pregnancy… so my anxiety is in over drive… My question is can you guys share some picture proof genetics defy the odds for us :heart:
