While creating genetically modified organisms, genetic barriers are not respected. How this can be dangerous in the long run?
Genetic pollution. The ecological imbalance may occur due to transferring of transgenes from one organism to another. Formation of Superweeds. Due to the introduction of weedicide genes in crops, there is a danger that any such crop may itself become superweed. Formation of super insecticides. Foreign proteins formed with foreign genes may get attacked by the defense system of the organism leading to the formation of defective biochemicals, Transgenes may exhibit changes in their expressivity after attaining certain age and change in environment.
