I've read this thread with interest but I'm not a biologist so still need help please ....Q1: Is every seed in any tomato genetically identical to all the others in the same single fruit?Q2: For something like Crimson Crush, how many tomatoes would you have to take for seed to have say a 90% probability of one being from the 1/16th group that has inherited both the PH2 and PH3 genes?ThanksBaffled of LoughboroughEdited to add: Is it really only 1/16th of the population that has both genes from its parents? Oh you guys, I haven't had enough coffee yet to get my head around this.** back to drawing on bits of paper **
And you don't need many tomatoes to do this because 9 out of 16 of the F2s are at least as good as the original F1s. But it does assume self pollination.And you can't tell which ones you've got until they've made a plant.Ooooooo - you know, this dehybridisation business can't be easy.
All the seeds from an F1 will be almost identical because there's very little genetic diversity in the parents, but it's probably safe to assume there will be at least a little. They're not clones. The same goes for any tomato, F1 or otherwise, since they're inbreeders. Every variety is likely to be descended from a single common parent. The only exception would be a plant which had crossed, whether deliberately or otherwise.
