I would recommend throwing these seeds away. They are a result of "selfing"--the female plant hermied (produced male flowers) and produced seeds. This is common with fem plants and is an undesirable trait. The resulting seeds will most likely hermie also.
Hmmm . . . I hate to disagree, THG, but IMO it is the seedbanks that are mainly to blame. I am tempted to take a pic of a certain strain that I am watching go from male to female right now. From seed I bought you-know-where recently. Its offspring would almost certainly be all female, but who cares?
