Selfed Seeds, I need help.

I just wonder if somebody could tell me what are some of the benefits (or lack thereof) of S1 ("selfed" seeds) seeds?? Also, I know that most F1's are quite uniform and that they say F2's are less uniform.. So, I know what an F2 is but what is their importance?
..I guess I just need to read up some more but I'm not rally finding the answers I'm looking for.

True F1's are uniform, people often cross related plants and call them F1's - they're not. F2's are where you find the unique genetic combinations you might be looking for in an attempt to lock down a new breed.

S1's are going to have certain recessive traits locked down, often these include desirable traits which is why sometimes S1's are popular. But it will also lock down undesirable traits. It's the ultimate form of inbreeding. Look into Luther Burbank and Mendel.

i've grown out a couple of S1's that came from a hermie mishap
1 out of the 2 was very close to the mother's traits, except it had no hermie trait, and was very nice, kind of like mom without the hermie attitude
the other was a 'brat', kind of a foul tasting beast that would gag most, looked OK during the grow
S1's of certain elite cuts get made from time to time, kind of a clone in seed form, or so it is hoped
it can happen, i've seen it on a small scale, though i could have been lucky

It's not a clone.

If you have XxYyooppaass genome the last part being recessive, that last part will remain unchanged from a selfed plant to it's offspring, but the first 2 genetic combinations have dominant and recessive alleles. There will be variation there in the classic 25/50/25 from both. Of course there's actually more variation because you're doing that multiple times over and there are codominant and corecessive genes etc. The cannabis genome actually contains approximately 20,000 alleles and it would be very difficult to get an exact copy of the mother because of it (unless you clone it).

indeed, 'clone' was being used loosely, better to say a very close pheno to the parent
which is what buyers of S1 seeds are hoping for
