    Don't think I can help you on this one sorry. If you do a cross with a write and a pink flower along with the asumsion that there is incomplete dominance. I want the ratio to be 1:1 between white and pink. while when I do the ratio on your observation I get 1:1;>0,05 ≈ 0 for red, pink and white.

    Red =245 so the percentage most be: Percentage red=(245/500*)100 percent is around 49 percent Percentage pink=(210/500)*100 percent is around 42 percent Percentage white=(45/500)*100 percent is around 9 percent the outcome is: 49:42:9. (divide with 49): 1:6/7:9/49 @Frostbite should i say that then?

    That is what I get just be looking at it. But it does not match the output for a white/pink flower cross... might just be I misunderstand everything.
