If there could be determined that the mitochondria produce some substance that is passed on to the next generation and also that that generation pases it also to their generation as F2, then that could interest me. However, I have not read of any experiments that had that happen.

Have you read about any of this stuff?
http://en.wikipedia.org/wiki/Epigenetic
(I can't believe I'm linking to wikipedia)Most of it is about changes within the lifespan of an organism but if you scroll down there's an example of a multigenerational effect - Lamarck in fact. Not quite as dramatic as a giraffe's neck (or an elephant's trunk stretched by a crocodile) but a long way from tall and short peas. Pretty cool in fact. Maybe we'll get lucky and someone will post some better links.
