Last time I was taught about biology, selective breeding was a process through which, over a long period of time, individuals with favorable traits were multiplied in order to increase the prevalence of such traits.
The genes were already introduced, hence, no modification. Already existing characteristics were allowed to further express and refine.
Genetic modification, to my understanding, implies introducing genetic information into the genome of an organism to produce another with traits previously completely absent in the species.
Selection vs manipulation.
I’ll concede there are a few cases where the lines blurr, like the golden rice, where a gene that codified the production of vitamin A in the grain was/is already inactive or so receassive, in order to have it express again would require gene manipulation but I think a selective production program was put forward in an attempt to bring out that gene again.
Can we get a geneticist here?
