Everything Trousers said above is correct.
First of all, **ALL** cannabis plants (male or female) have the ability to make male flowers as a natural survival mechanism hard-coded into their DNA. Virtually every wild female cannabis plant in nature will put out some male flowers at the end of flowering, if not sooner. This is NORMAL. With modern medical/drug strains, the tendency of female plants to do this has been deliberately suppressed by selective breeding, that's all. The reason, of course, is that seedless crops are what's most desirable from a medical/drug standpoint.
But even female plants from these strains can still put out male flowers under the right (/wrong) conditions: light stress (light during the "dark" period, or a variety of other light patterns during flowering), temperature stress, nutrient stress, being grown long past their maturity date (this has been called "rodelization"), or use of external chemical or hormonal agents (colloidal silver, gibberelic acid), etc.
Next, unlike human beings that are normally either "only male" or "only female" cannabis plants in nature can show a wide variety of sexual phenotypes. You can have genetically female plants that will show a. all female flowers, b. mostly female flowers, but with rare male flowers, c. lots of male AND female flowers. On top of this, there are different phenotypes of flower production: Single male flowers can appear within clusters of female flowers, they can appear as clusters of all male flowers on otherwise female plants, and (if I remember right) in some cases you can even have "intersex" flowers with both male and female characteristics. The issue of "hermies" is a bit complicated, but the point is, what most people call "hermie" plants are actually NORMAL for the species.
The answer to the original question is, if you cross a normal female plant with pollen that comes from a female plant with a few male flowers on it, the offspring will all be females. The simplified genetic explanation of why is that female plants contain only "X" chromosomes and no amount of crossing them can ever create a male plant with a "Y" chromosome.
The next question is, if you create "feminized" seeds by crossing two female plants, will the offspring be prone to "go hermie" (ie make male flowers)? I think this is what everyone is really concerned about. . .that if you use a "hermie" for breeding, that line will be plagued with them from that point onward.
The answer to this question, is that it depends mostly on the GENETICS of the original parents. Stress is not genetically inherited, and so far as I know the "feminization" process doesn't alter a plants DNA. Again, its perfectly normal for female cannabis plants to make male flowers and fertilize other female plants, and this sort of thing happens all the time in nature.
If both female parents are properly bred medical/drug strains that are resistant to making male flowers, then the offspring should be too, irrespective of what exact mechanism triggered the "father" to make male flowers.
If either female parent is susceptible to "going hermie" from light or heat stress, then its likely the same trait will be passed onto some or all of the offspring. If both parents are susceptible, its almost a given that all offspring will be too. And of course of either or both female parents are prone to making male flowers normally (ie without any special stress), then of course the offspring will likely inherit that trait too.
In my opinion, THIS is why you have to be careful about using pollen from female plants for breeding. If you're making an otherwise hermie-resistant female plant create pollen using chemical or hormonal stress, the offspring should also be hermie resistant. But if you're "promiscuously" applying pollen from a "slutty" female plant that is prone to making male flowers early in flowering, or due to light stress, then you're going to be creating offspring with the same tendency.
