Agriculture has relied on plant breeding to improve genetics since the first domestication of agricultural plants 10,000 years ago. More recently, Gregor Mendel and his hybridization experiments on peas led to what we know as modern genetics. The rise in recombinantDNA technology has opened up many possibilities in plant breeding, including Roundup Ready technology and crop varieties designed to resist a number of pests. At the same time, governments and the private sector have sought to institute regulations for handling the releases of new biotechnology to ensure the technologies will have limited environmental impacts and provide safe foods to the …
