Biotechnology expert witnesses may write reports on genetic engineering, biochemical engineering, and more. Here, the Food and Agriculture Organization of the United Nations describes biotechnology:
There is a wide array of “biotechnologies” with different techniques and applications. The Convention on Biological Diversity (CBD) defines biotechnology as: “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use”.
Interpreted in this broad sense, the definition of biotechnology covers many of the tools and techniques that are commonplace in agriculture and food production. Interpreted in a narrow sense, which considers only the new DNA techniques, molecular biology and reproductive technological applications, the definition covers a range of different technologies such as gene manipulation and gene transfer, DNA typing and cloning of plants and animals.
