možno to nie je až tak nepochopiteľné. Stále je tu riziko:
"However, GURTs may not be able to completely limit genetic drift, which reintroduces the serious concern about modified genes making their way into wild type populations in spite of the GURTs. Concerns have been raised about the effectiveness of GURTs in consistently producing sterile progeny. One study shows that in reality only ninety percent of GURTs are successful in creating sterile progeny, with ten percent of plants capable of passing on the GM genetic material. So, GURTs may be capable of limiting genetic drift, but it seems they cannot entirely prevent it. This significantly reduces the environmental benefit of using GURTs to reduce genetic drift."
