Cisgenic crops have genes of the same kind engineered into them. They differ from transgenic crops in which unrelated genes are introduced. The latter poses more risks for the environment and public health, says the European Food Safety Authority (EFSA). A point of criticism from opposers is that genes of the same kind enter randomly into the genome of the crop during genetic modification. That's right, says the EFSA, and adds that this also happens in conventional breeding.
