Marker-Assisted Selection (MAS) is a technique used in plant and animal breeding that helps identify desirable traits more efficiently. By using specific DNA markers associated with these traits, breeders can select individuals that carry the desired genetic characteristics without waiting for them to mature or produce offspring. This accelerates the breeding process and increases the chances of success. MAS is particularly useful in improving crops like corn and wheat, where traits such as disease resistance or drought tolerance are essential. It allows for more precise breeding decisions, ultimately leading to better yields and more resilient varieties that can adapt to changing environmental conditions.
