it was probably a self-pollinated or a nanner from another plant in crop pollinated it... this is why ppl usually say stay away from bag seeds. if it hermied under normal conditions in order for that seed to exist, it's abad trait to pass down and increases chances of hermie in offspring.
fem seeds come from stressing the plant by blocking bonding sites with silver ions or STS? whatver the specifics.. the point is the plant doesn't herm on its own... we force it, so it's not a hermie trait so to speak like explained above.
Not all doom and gloom. Doesn't guarantee anything... but... it's probably same strain as what was in the bag. assuming this is from some mass production facility and not someone's basement. the latter could be any hybrid of what was grown in same room with higher percentage it was self-pollinated or from a 'closer' plant than one further away. just probabilities....
the inbreeding could have caused the funky leaves (asymmetry). think some nute-related things can cause some oddities in leaf development? but not 100% on that off top of my head.
i doubt it is an autoflower unless it came from an autoflower... and that doesn't guarantee it will be an autoflower seed, either. to get 100% 'auto' offspring trait, takes a certain process to get that uniformity... a random pollination may not be 100% auto offsprings in a room of autos. a punnet square can explain better... and 3-4 generations of plants, i believe. probalby gotta work backard from ratios of observed outcomes to know.. or some other hindsight.
