Many of our foods are being "irradiated", thus rendering the seeds genetically different from the original plant. I was reading a column the other day warning that much of our garlic is irradiated. Plants are also being engineered to only produce the fruit part and NO seed. For example, seedless watermelons and oranges. http://www.organicconsumers.org/irradlink.cfmhttp://www.organicconsumers.org/irrad/sproutcomments.cfm
