A mother with blonde hair who has a child with a man who is a hybrid for brown. Blonde hair?

In genetics, hair color is influenced by multiple genes, with brown hair typically being dominant over blonde. If a mother with blonde hair has a child with a man who is a hybrid (heterozygous) for brown hair, the child could inherit either the blonde or brown allele from each parent. This means there's a possibility for the child to have either blonde hair (if they inherit blonde from both parents) or brown hair (if they inherit brown from the father). The exact outcome will depend on the specific genetic combinations inherited from both parents.
