The domestication and artificial selection of production animals has led to a diverse range of phenotype variation that affects tremendous variety of tissues, organs and body systems. Understanding the underlying genomic mechanisms giving rise to these phenotypes has enhanced our understanding of physiology, reproduction, artificial selection, genetics and bioinformatics. Genomic signals associated with artificial selection and adaptation help elucidate genes, alleles and chromosomal regions implicated in modulating important production traits. These phenotypes include behavior, carcass traits, dairy associated phenotypes, egg production, growth rates, to high altitude adaptation, survival in harsh climates, decreased resistance to infectious disease and optimization for enhanced feed conversion.
Animal genomes encoded a vast and complex set of biological instructions that inform the developmental, anatomical and physiological phenotypes. These phenotypes ultimately give rise to the desirable and undesirable traits observed in production animals, and form the foundation of artificial selection processes to further refine these phenotypes. The focus on artificial selection, selective sweeps, signatures of selection and production animal phenotypes provides a rich and interesting intersection to further understand how genomes give rise to physiological traits and the diverse biological processes required to achieve them. The goal of this special research topic is to explore the vast genomic mechanisms that control animal phenotypes and highlight the specific variations that underlie them. An increased understanding of how genomes encode selection will undoubtedly facilitate an increased understanding of the molecular and biochemical phenotypes that inform the tissue and organ phenotypes at the organism level.
