the traits that Mendel used to distinguish his peas, and the molecular markers we can now use are conceptually identical. variations in the DNA sequence. they are transmitted in EXACTLY the same way.
the difference is that if you have DNA sequence to design PCR primers you can pool and muliplex and find your one in however many million you need events to achieve your goal.
if you know folks that are already
I repeat that knocking out (down) the THC synthase loci to achieve “hemp” is gonna easier that moving a bunch of genes and getting them to play nice in the same plant.
been there. done that. when it was fucking unheard of.
