... takes selective breeding a step further, Scientist are learning how to identify genes and recognize which genes control the development of which characteristics. They are now able to breed offspring by transporting the desirable genes from one plant to another. There are concerns that genetic modified crops could escape from their fields and growing more vigorously then other crops and wild ... herbicide resistance. Concerns have been expressed that eating genetic modified food could cause health problems in humans, including the development of harmful antibiotic resistant microorganisms...
