The current review article aims to briefly highlight the most important genomics technologies used to create breeds that are productive and well-adapted in a given circumstance. It also emphasizes the role of bioinformatics in modern chicken breeding. Advances in genomics information technologies are valuable opportunities for achieving the required improvement, but their implementation implies access to technical and financial resources with suitable adjustment in the local situation. The majority of domesticated livestock species are chickens. The foundation for genomics has been established by the dramatic advancement of molecular genetics. The applications of the newest generations of molecular markers are incredible tools for farm animals' genetic advancement. These markers offer more precise genomic data and an improved understanding of the animal genetic resources. Genomics tools are essential for the accurate, fast, and efficient breeding of animals. Compared to other domesticated animals, chicken is widely accepted and has little to no taboos in terms of cultures, religions, and society. About resolving the issues of food security in a world affected by climatic change and human population expansion, it offers a unique genetic resource due to its resilience to a variety of environmental circumstances and demonstrated potential for breeding improvement. The historical evolutionary history of the chicken has been reconstructed thanks to recent investigations that have revealed new information about its DNA. Breeders of chickens must move more quickly towards creating and choosing enhanced breeds that can withstand environmental stress without compromising production and productivity.
