Say you buy a 10 pack of straight seeds, it's a line that's been worked so should have some level of consistency, lets say 5 phenos just for shits. You pick 1 male and 1 female and breed them, not necessarily picking for a phenotype just random. Will the offspring of this cross produce seeds inclusive of all 5 parent phenos being that it's just one generation? Or is it likely that you would cull some of the genetic variation within 1 breeding cycle?
