Solution:

Right handedness is dominant over left handedness. If both the parents are right handed, then they must have either pure right handed genotype or hybrid right handed. But if they are having a left handed child, then the genotype of the child is . So the one recessive gene comes from the father and the other gene comes from the mother. Hence both the parents should have gene in their genotype. Hence the probable genotype of both the parents is and , i.e., hybrid right handedness.
