As a geneticist with a focus on human genetics, I can provide an explanation for how it is possible for parents with brown hair to have a blonde baby.
Hair color is determined by multiple genes, with the primary ones being the melanocortin 1 receptor (MC1R) gene and other genes involved in the production and distribution of melanin, the pigment that gives color to our hair, skin, and eyes. Brown hair results from the production of a type of melanin called eumelanin, while blonde hair is due to a lower concentration of eumelanin.
Parents with brown hair may carry recessive genes for blonde hair that they do not express themselves but can pass on to their offspring. If both parents have one copy of the recessive blonde hair gene, there is a 25% chance with each pregnancy that they will have a child who inherits two copies of the gene, one from each parent, resulting in blonde hair.
It's also important to note that hair color can be influenced by other factors, such as the environment and the interaction of multiple genes. Additionally, the perception of hair color can change over time as a child grows, and what may initially appear as blonde hair could darken to brown as the child matures.

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.
