Genomic selection is a cutting-edge field in plant and animal breeding that involves using DNA markers to predict the genetic merit of individuals for various traits. This method allows breeders to select the best candidates for breeding with high accuracy and efficiency, speeding up the process of improving desirable traits in crops, livestock, and other organisms. Genomic selection has revolutionized breeding programs worldwide by enabling the identification of superior individuals based on their genetic potential rather than traditional methods relying on phenotype alone. By utilizing the information contained in the entire genome, genomic selection has the potential to significantly enhance the genetic gain in breeding programs and accelerate the development of new and improved varieties.
