As a geneticist with a focus on human genetics, I can explain the complexities of hair color inheritance. Hair color is determined by multiple genes, with the *melanocortin 1 receptor (MC1R) gene* being one of the most significant. This gene influences the production of melanin, the pigment responsible for hair color. There are also other genes that contribute to the final hair color a person has.
Black hair typically results from the production of a type of melanin called eumelanin, while blonde hair is associated with a different type called pheomelanin. The production of these pigments is influenced by the combination of alleles (different forms of a gene) that a person inherits from their parents.
Now, for two parents with black hair to have a blonde child, several genetic factors would have to align. It's possible if both parents carry recessive alleles for blonde hair that are not expressed in their own hair color (they are carriers) but are passed on to their child. This would require both parents to have a specific combination of alleles that, when combined, result in the expression of blonde hair in their offspring.
It's also important to note that environmental factors can influence the final expression of hair color, although these are less significant than genetic factors.
In conclusion, while it's less common, it is possible for parents with black hair to have a blonde child if the genetic conditions are right.

A dark haired parent and a light haired parent will often have a child with a color in between. Black + Blonde = Brown! So all in all the answer to your question is neither! Blonde hair, brown hair, blue eye, browns eyes ��none of those traits are dominant or recessive as they are not due to a single gene.
