i said that also! I dunno how i did overall, but i can at least say that i think i did the dyhybrid cross alright! I knew the ratios, so i busted my ass, pencil, and rubber trying to come up with a combination that would work.

However i may have got the offspring genotypes wrong as i only did a 2 by 4 cross which only accounted for half of the offspring genotypes, but still gave the same ratios. I hope it all will be ok in the end :smile:
