Detailed explanation-1: -The earliest example of biotechnology is the domestication of plants and animals. Domestication began over 10, 000 years ago when our ancestors started keeping plants as a reliable source of food. Rice, barley and wheat were among the first domesticated plants.
Detailed explanation-2: -Selective breeding was likely the earliest form of biotechnology used by humans to improve the genetic characteristics of plants and animals. Biotechnology includes any use of science or technology to alter the genetic characteristics of a particular plant or animal.
Detailed explanation-3: -Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.
Detailed explanation-4: -Since the first successful commercialization of a biotechnology-derived crop in the 1990s, many new crop varieties have been developed and made available to U.S. farmers and farmers worldwide.
