actually that is incorrect
a very limited number of seeds may carry the cultivar trait.
how else do you think we get many of the hybrid cultivars that are crossed between two
a high percent, usually all will be typical but there are instances where it passes through seed.
EDIT:
Although if it does contain only a few of the traits, it is not the cultivar
it must match description perfectly and as far as i know the only ones that can be done easily are
Dentate Traps
Justina Davis
or other color variations so long as it matches perfectly with cultivar description
