Depending on the breeder that did the initial seeds that spawned that mother, it's possible, but not a guarantee given the other geno/phenotypes possible at any point until all the 'wanted' traits have such a high % that anything else likely to show is almost 0%.

Figong that's good, sorry my simple mind doesn't follow, ill dumb it down for the op as well as I and tell me if that's what your saying....
Only if the mother is true breeding will the seeds be the same otherwise you get a range of phenos as if you had the moms seeds again?

2 true breeding strains form an actual f1 hybrid... If you don't have 2 true breeding strains, you can see more variation...

thats is called selfing, it has been known to generate herms.
if you grew 2 seeds from same strain and used CS on one(or a clone of one) to hit the other with pollen, this is called in breeding and will generate stable fem seeds.

Is why I recommended the Cannabis Breeder's Bible written by Greg, would definitely cover just about every genetics question one could ask.

its good book definitely a good read, worth reading for the start of understanding genetics. sad thing is its, outdated, there is so much info not covered. and whats even worse no revisions have been made or another book like it with the full info. i really wish there was something a little more updated.Is why I recommended the Cannabis Breeder's Bible written by Greg, would definitely cover just about every genetics question one could ask.

Agreed, a solid update would be nice as it's 7 or 8 years old.. from memory, but I do also agree that having no background in genetics whatsoever.. someone would definitely gain a bit of knowledge in terms of breeding should they have none whatsoever to start.
No it will NOT be a clone or essentially equivalent to a clone. Selfing a plant will not produce an identical plant unless it has been fully inbred to be 100% homozygous.
It will be very similar to the mother plant, which can be nice for production of seed stock, but horrific for a selfed breeding line since most of us do not want selection of hermi traits in our progeny.

Proper fem seed production wouldn't increase the chance of herm traits, short of a genetic anomoly.. or irradiating your seeds to try to force induce a new set of phenos that may not otherwise have any chance of appearing.
Fact One:
There are genetic tendencies for different strains which under environmental stress produce more or less hermis to the same environmental stress.
Fact Two:
If you continually select strains through hermi production of seeds, you are inherently selecting for those genetics which responded to the environmental stress.
Irregardless of the environmental stress, even though you really wanted to select for other characteristics. Its part of the population and you are inadvertantly keeping them in the selected population.
This has nothing to do with fem seed production for use by production growers. The horrific was specifically referring to creating fem'd seeds and then using those seed to derive selected breeding stock. BIg Difference

If you use colloidal silver you are not stressing a plant, you are activating hormones. That is not going to change the genetics. that is not selecting for plants that responded to the environmental stress at all. All female cannabis plants can be tricked or stressed into producing male flowers.
No one has been able to convince me that breeding with feminized seeds is a bad idea.
I have selfed plants and not seen one "hermie."
Breeders back cross and self varieties all the time.

I have seen reports from reputable breeders that there is variability to the response to CS. Some strains or individuals female resist producing male flowers.
Irregardless of the specific mode of action of CS, if there is consistent variability in a population its possible to be selectable.

The selfing itself is unlikely to cause hermies. However the selfing can cause a homozygous set of genes in the pairs that may influence hermies.
Basically this means if you have a strain which has hermie tendencies, then the self'd progeny may have some individuals with stronger hemie tendencies and some with less.

Bring me a female and I will make it produce male flowers.
Making a female produce male flowers does not change the dna.
A female plant that produces male flowers is not a real hermaphrodite.
Breeders may come up with a variety that is easily stressed if not grown under the proper conditions.
