Making feminised seeds

I'm pretty sure the original poster realizes that "mothers" contribute genetically but I think they're curious if there might be certain markers/characteristics that carry ONLY in the pollen or ONLY from the flower side. Sadly, I don't know that answer and honestly I'd be suspicious of anyone who claimed to know definitively. We don't know enough about cannabis genetically to make those kind of calls. What I DO know though is if you're crossing two totally different strains your gonna create F1 hybrids that should display some hybrid vigor but there is also gonna be a lot of genetic variations in your seeds, aka several different phenotypes. If there are certain traits you're after you'll need to identify the phenos that carry it and breed those with themselves to reinforce it(aka stabilize the genetics).
