The authors of the 2004 study say that they see no reason to assume that "races" represent any units of relevance for understanding human genetic history. Analysis of the complete human mtDNA genome: methodology and inferences for human evolution. Whether both parents have the same or similar skin tones, or one parent is lighter or darker than the other, theres a range of tones your babys skin can have.

If both parents have the same hair color, there is an overwhelming (like 95%+) chance that the baby will have that hair color. Some content creators may "geneticize" custom skin tones. However, as infants become toddlers, their hair tends to lighten again as they grow older. What can lice tell us about human evolution?
