Why would a wheat farmer engage in artificial selection?

A wheat farmer would engage in artificial selection primarily to develop crops that are disease and insect resistant. This practice allows the farmer to choose specific plants with desirable traits, such as resilience against pests and diseases, and propagate them for future planting. By selecting for these beneficial characteristics, the farmer can enhance crop yields, reduce losses caused by environmental stresses, and improve the overall quality and sustainability of the crop.

This method has been a cornerstone of agricultural practices, as it enables farmers to tailor crops to their specific growing conditions and challenges, ultimately ensuring better food security and reduced reliance on chemical pest control methods. The focus on resistance traits is essential in modern agriculture where challenges like climate change, evolving pests, and diseases pose significant threats to food production.
