What would be the independent and dependent variables in this problem?

We had a lab where we counted up the different types of corn kernels on a corn (purple wrinkled, purple smooth, cream wrinkled, and cream smooth). THis was the F2 generation. Using this info, we needed to find the F1 and P generation. I'm having trouble with my hypotheses - what would be the independent and dependent variables in this situation? Also, how should I write my hypothesis? It needs to flow like "If (ind. variable), then (dep. variable)."
