My baby is biracial what will it's ethnicity be considered?

I am of African descent I have Caucasian ancestors but my African traits are more dominate so that is what I classify myself as and my boyfriend is Hispanic, he identifies with being Mexican even though he has Puerto Rican ancestors. We're both mixed up lbs. I'm just curious as to what our baby will be classified as. Does anyone have biracial children? Please share your stories I'd love to hear it.
