Really depends on where the seeds came from, mother,....etc.... way to many variables! Seeds are a guessing game, your pretty much playing a roulette game, either one could go, mabye all, none, or some...etc......But besides all that i usully try to think of at least a 50/50 ratio (just in case) so whatever you are planning on growing double the seeds up, but thats just me! Hope that helps ya some!
