Dear Student ,

The study shows that light colored eye is a dominant trait because this trait appears frequently in every generation. Dominant trait means trait that has a capability to overcome the effect of recessive trait when both are present. According to the study light eye colored parents has light eye colored children which shows that this trait overcomes the other trait (which has to be recessive), that makes it dominant.
