I'm not sure what Carol means by "not based in epigenetic change".

Pardon a rather muddled analogy...

If we think of the genes that a plant has as a hand of cards that the plant plays, the cards that the plant will play depend on factors like climate, soil, etc. So the cards being played may change, but the hand the plant was originally dealt was the hand the plant was dealt - if it doesn't have an ace, there will be no aces in the offspring - when it gets crossed or otherwise produces offspring through sexual reproduction the cards are coming out of that hand, as well as that of one other player. I do think that your best plants among the offspring will have received the best cards (genes) for your soil and climate, so yes, epigenetics does affect what you get. But there's nothing there you wouldn't have gotten through chance anyway, because the plant can only play the cards it has. It's just that not all cards get played in every round...

... clear as mud?  :o I thought so.
