yep.
thats how it works.
breed for the traits u want, hieght width potency branches smell flowering time.
good luck
a hybrid is any cross between two plants of non identical genetics. although even 2 seeds from the same branch can have wildly different properties due to the way rna combines to form subtle variations.
theres species spacific hybrids. like crossing 2 differant strains of pot.
or cross hybridization where 2 plants of differant species are cross polinated to see what occurs, like cucumber and squash, they can easily cross (happens in my garden every year, i havent decided on squacumbers, or cuquash) sometimes it works sometimes it doesnt, mostly reliant on chromosome count and if the internal workings of the plants is close enough. although even then they say most cross hybrids are sterile and will never produce seed
thats how we got seedless watermelon
and the reason bannanas have no seed. (<----- that is if im remebering corectly)
someone feel free to correct me
