Question on Genetics and Feminized Seeds

I'm on the second grow with seeds from a friend's bag of really good skunky stuff. He only had about a dozen seeds, but all the ones he gave me have turned out to be females.

I'm not an expert on genetics and I was wondering this: If a plant grown from a feminized seed gets pollinated, will the seeds it produces be mostly female? Or am I just lucky that 8 out of 8 have all been female?

Thanks

Your just lucky.

I better go buy a couple lottery tickets.
