I am not sure what di-hybrid crossing is, but if it is filling out the punet square I do know how to do that my biggest problem is knowing how to break up the gentics into the sectons for the side of the square after that reading the square is easy. For example if I were to breed a Pastel Clown to a Pastel Clown. I know I would have a normal Pastel gene: (Pp) and I would have a hom Clown-for the clown trait to show it has to be hom. from what I have read- (CC)Then I would assume that you could have a possiblity of hets in the coding as well (Cc)Then would the other gene be just a normal broken off of the Pastel?

I think my biggest problem in the gentics is how to break the parents gentics, I also get confused as to how one parent pass 2 gens in to the egg, such as seen in the bumble bee breeding to normal.
