Marker-assisted selection is a technique used in plant and animal breeding that utilizes specific DNA markers to identify desirable traits. By analyzing these markers, breeders can select individuals that are more likely to pass on beneficial characteristics, such as disease resistance or improved yield, to their offspring. This method speeds up the breeding process compared to traditional selection methods. This approach is particularly useful in crops like maize and wheat, where traits can be complex and influenced by multiple genes. By focusing on genetic markers, breeders can make more informed decisions, ultimately leading to improved varieties that meet agricultural demands more efficiently.
