Second, chromosomes are bundles of DNA. Genes actually produce proteins. Chromosomes are how cells arrange their DNA, and the chromosomes must be unwound in order for the genes to be transcribed into RNA. There are no "gliadin chromosomes" or "glutelin chromosomes". There are "gliadin genes" and "glutelin genes". 6 copies in the most common wheat, because it has 6 copies of it's DNA....but just because there's multiple copies doesn't mean it produces more - gene regulation is far more complex. For example, women do not have double the proteins in the genes on the X chromosome - one copy of each gene is inactive.
As for the passage:
Wheat is one of the few crops that has not had genetic engineering in commercial crops. The existing varieties are results of selective breeding. Just like a terrier vs a great dane. So there have not been "shenanigans by plant geneticists", because geneticists have yet to produce a commercial wheat crop. Unless you're gonna call ancient Sumerians "geneticists" too.
So...the guy is now saying gliadin is new....but said something different in his book. So by his own admission he's lying either now or then. He also apparently doesn't understand that chromosomes and genes are different things.
And we should believe this guy because.......?
