Instructor solution
Artificial selection has been used to develop modern domesticated wheat varieties by selecting for traits such as higher yield, disease resistance, and adaptability to different climates. This process involves cross-breeding plants with desirable traits over multiple generations. While this has led to significant improvements in crop productivity, it has also resulted in a reduction of genetic diversity. The focus on specific traits often leads to the exclusion of other genetic variations, making the crop more susceptible to diseases and environmental changes.
