What is marker assisted selection?

Marker-assisted selection (MAS) is a biotechnological process used in breeding programs that utilizes molecular markers to identify desirable traits in plants or animals. By examining specific DNA sequences associated with these traits, breeders can select individuals that are more likely to exhibit favorable characteristics, thereby accelerating the breeding process. This technique enhances efficiency and precision compared to traditional selection methods, ultimately leading to improved crop yields or livestock quality. MAS is particularly valuable in the development of crops resistant to diseases or environmental stresses.
