The world's population demand and animal output are significantly out of balance. Although traditional breeding techniques have been successful in selecting animal populations for a variety of traits with economic significance, the reliability of breeding value has always been in doubt. According to simulation and experiment data, genomic selection for young animals without own performance can predict breeding values with good accuracy. Genetic markers that cover the entire genome are employed in genomic selection, a sort of marker-assisted selection, to ensure that all loci for quantitative traits are in linkage disequilibrium with at least one marker. Early animal selection enables the development of innovative breeding techniques that increase genetic advancement while decreasing costs. The future of animal breeding companies lies in genomic selection, which increases genetic gain by reducing genetic interval and enhancing reliability. To regulate long-term genetic gain and increase the precision of genomic estimated value, more study is needed. An overview of the developments in genomic selection and its use in animal breeding was the goal of this paper.
