Detailed explanation-1: -So the answer is a Mark will have brown hair.
Detailed explanation-2: -It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up.
Detailed explanation-3: -The Truth About Dominant and Recessive Genes Each parent carries two alleles (gene variants) for hair color. Blonde hair is a recessive gene and brown hair is a dominant gene.
