You mean if I buy a pack of f1 seeds I am not going to get a copy of the mother cut in that pack??? GTFO lol. Its not hard to understand that if a breeders goal is stability they will worm the line, but if they just want to cross out a clone only to make it available in seed form then dont expect to get an exact representation of the mother or father. It will be a mix ie. MmxPp=1MP, 1mp, 1Mp, 1mP. And thats to keep it simple for genetic mixing, there is hella more shit that plays a role in how genes meet than just making the cross on paper so again to expect either parent to show through is not having real expectations of a f1 cross.
Thats just what it is, really has less to do with the breeder but more the person buying f1s expecting the clone only keeper out of it.
