for example, u have 2 females, both turned purple, 1 gave u the high u wanted and the other gave u a headache or someshit unwanted. how do u reuse that 1 plants genetics?
You might want too look into some basic genetics like punnet squares, dominant and
recessive alleles, phenotypes and genotypes, and how different traits are determined.
For example, let's say x is the trait you want (recessive) and X is the trait that is
unwanted (dominant)...The punnet square might look something like this if you crossed
a plant with xx with plant that is heterozygous dominant for the unwanted trait (xx & Xx):
X x
--========
x | Xx | Xx |
--|___|____|
x | Xx | xx |
----------------
25 % of your seeds (basically) will be homozygous recessive for the trait, meaning that if
a dominant allele is introduced in another cross-breeding, you will have a different trait.
Basically from there you're going to have to try to systematically breeding different seeds
to find out which ones are xx for the trait, and when xx is bred with xx, all the resulting seeds
will be xx for the trait, meaning that all seeds from a xx & xx cross will have the desired trait.
Also, by crossing a strain that it is homozygous dominant with any other strain you will receive
seeds that always have the dominant trait(But some of them will be heterozygous and you can
breed these to have 25% of getting the recessive allele).
That being said the only problem with such a trait as the high is that it is controlled by many
different factors and many different alleles, making it nearly impossible to cross-breed until
perfection. It's a hit and miss thing.
