uhm, though the graph doesn't match the problem, I remember doing this when I was in bio. If you are looking for the genome, it would be something along the lines of Gg, or GG (G=green dominant, g=yellow recessive)
I hope this is what you need!
An eukaryote is a cell that has organelles like the mitochondria, nucleous, etc.. A prokaryote is a cell with no organelles, meaning that the dna flows freely in it. A way i remember which is which, is that the "pro" in prokaryote rhymes with "no" which means "no organelles"
