I can't seem to remember enough from my college genetics (maybe because it was in 1970) to answer my own question -- I have one Pruden's Purple tomato plant growing, which has a lot of variation in the "form" of the tomatoes; some are nice and smoothly rounded, others very oddly shaped (nothing new there for this variety). My question is, will there be more likelihood of getting a higher percentage of the nicely shaped fruit if I save seed from one like that, or would that only work if I had, say, a dozen different plants and selected fruit from a plant that had a higher percentage of the nice tomatoes ? It actually seems to me that the seed from all the tomatoes on one plant should have the same genetic makeup, I'm just kind of hoping I'm wrong...
Hope this makes sense to someone !
