Yes, to lil stinkpot's point.
Cultivars like Dente, Red Dragon, Red Piranha, etc were probably selectivly bred across many generations to arrive at thier present day characteristics.
My guess is you would not see anything near the characteristics of some of these cultivars with even a very large number of typical seeds. You would see some with distinct characteristics (vigorous, short hars, long hairs, more red, less red, etc...) but probably none near the extremes that some of these cultivars have.
