Well, the diprefix simply means two. And what dihybrid crosses involve is they involve the study, study of two different types of traits. Now, to demonstrate what we mean by dihybrid cross, let's suppose we have the following scenario. Let's suppose we have P plans, and our goal is to study two different types of traits within that P plan. So we want to study the height of that pea plan as well as the seed color of that pea plan. So our two traits are height and seed color.
