Although in reality the inheritance of cleft chin (e.g., the deep chin dimple seen in Ben Aimeck) is slightly more complicated, for now let's assume that the presence or absence of a cleft chin is determined by one gene. By studying pedigrees, we know that no child possesses a cleft chin unless at least one parent does (either the mom or the dad). Hint: Based on that last statement, you should now know the mode of inheritance! What is it? (Remember Recessive traits can hide, but dominant traits never do! ) O Cleft chin is a dominant trait. O Cleft chin is a recessive trait.
