. . . Self pollination is different than cloning although cloning is also easily done on tomatos. A cutting produces a clone and we all know how easily tomato cuttings root. No matter how stable an heirloom is however there are slight differences in the DNA in each blossom; that's why you have to choose the plant you save seeds from carefully to keep the plants as true to the ideal as possible. . .
See it was the genetics I have a hard time comprehending - as well as an organism that is both male & female.
Okay, if the chromosomes carry both dominate and recessive genes (for all sorts of characteristics), then one can't really know which is going to show up in the pollen or ovum. Marshall used "D/r" letters. So, the parent plant may "look" like what you want but could have D/r genes. Both the male and female flower parts would carry that combination. Therefore, pollen and ovum could be "D" or "r" . . . Heck's fire that means this "perfect" male/female organism could be as untrustworthy as any mongrel !
Selective breeding is still critical to develop a variety that (at least) tends to breed true. Shoot! I thought tomatoes would be
easier than that and just throw duplicates of the parents unless hybridizing is involved!
I'm beginning to dislike tomatoes . . .
