How will the knowledge of heredity help us in maximizing the
crop production.

Answer:
Crop improvement, the engineering of plants for the benefit of humanity, is as old as agriculture itself. Some 10,000 years ago, primitive people made the transition from hunting and foraging to cultivating crops. With that switch began the continuous process of improving the plants on which we depend for food, fiber, and feed.
Throughout the milennia, two techniques have been used to improve crops, according to Lawrence Bogorad, a plant molecular biologist at Harvard University. The first is selection, which draws on the genetic variation inherent in plants. The earliest farmers selected plants having advantageous traits, such as those that bore the largest fruit or were the easiest to harvest. Perhaps through some rudimentary awareness that traits were passed from one generation to the next, the choicest plants and seeds were used to establish the next year's crop.
