DMPQ: Explain the Crop breeding and the introduction of GM crops for food production.

Conventional breeding, especially of crops, livestock and fish, focuses principally on increased productivity, increased resistance to diseases and pests, and enhanced quality with respect to nutrition and food processing. Advances in cellular genetics and cell biology methods in the 1960s contributed to the so-called ‘green revolution’ that significantly increased varieties of staple food crops containing … Read more
