theres nothing inherently wrong with f1 seeds, all it means is 2 distinct varieties have been bred to produce a third. an f1 seed will still produce fertile seeds itself but it wont breed true to type, it will revert back to one of its predecessors or similar. i have unwittingly bred f1 seed as im sure many of you have. if you plant a few varieties of runner bean near each other, you will end up with f1 beans, ready for next year. the bean wont be true to either of its parents.
dont confuse f1 with gm they are no where near.
gm means that a seed has had its genes added to in a laboratory, to cause a certain feature of the plant, in monsanto's case it manipulates the seed to not be affected by glyphosate (which is also a monsanto product) which enables farmers to use way much more glyphosate on the fields, literally wiping out all the seeds competition, and monsanto profits by the increased use of glyphosate, as well as the seed itself.
there are also gm seeds that have been produced to exude a 'natural' pesticide, with the intent of reducing the need for sprayed insecticide, this is the recently trialed variety that made the news in the uk. they obtained the gene i believe from an insect, isolated it and added it to the genes of the seed.
genetic modification in no way replicates natural selection or evolution.
only time will tell if those children will survive and if they do, what they will become.
