Hello. That is a tough question. I've started 10 reg seeds and got 9 males once and a different strain gave 8 females with 10 reg seeds. On the average I would say 8 reg seeds will get 4 females and 4 males. The old school trick is - where the seed was attached (not the pointy end) is a circle. if the circle is not perfectly round you have a good chance it's a male. If it's perfectly round it's probably a female. Hope that helps. Chuck.
