Yes, it is possible for two parents with brown and red hair to have a child with blonde hair, though it is not very common. Hair color is determined by multiple genes, and the inheritance of these genes can lead to a variety of outcomes. Both brown and red hair can carry recessive alleles that could result in a blonde-haired child if the child inherits the right combination of genes from both parents. For instance, if one or both parents carry a recessive blonde hair allele, there is a chance that the child could express that phenotype. However, the likelihood depends on the specific genetic background of the parents.
If 1 person had brown hair and another had red hair, could they have a blonde hair child?
