"what if the shape is very dependent on some non-genetic factor like weather, water or pure chance? "
Yes, that is something I wonder about, too. Many of the flowers on my plant were obviously doubled (as best I can describe it), and those always result in the strangely shaped tomatoes...
"Does one grain of pollen produce every seed in one fruit, or is the rule:
"one-grain-of-pollen = one seed"?"
And that is another interesting question... certainly in corn each kernel is the result of one grain of pollen (or at least that's the way I understand it - ?)
hmmmmm...
Maybe I'll just use the nicest ones for BLTs and get seed from the others and not worry about it...
