Quizplus · Accepted Answer

Michael has two genes for brown hair, which means he can only pass on a brown hair gene. Lisa has one dominant gene for blond hair and one recessive gene for blonde hair, but since brown hair is dominant over blond, any child will have brown hair. Therefore, the child will have a 100% chance of having brown hair.
