Abstract:
Traditional selective breeding relies on observable phenotypic traits. Recent advances in omics technologies (e.g., genomics, transcriptomics, proteomics, and metabolomics) have revolutionized phenotyping in animal genetic breeding by providing deeper insights into complex traits and improving the efficiency of breeding programs. This review summarizes the applications of omics-based phenotyping technologies to improve the phenotypic traits, such as meat, egg, milk and wool quality, as well as yield, disease resistance and stress tolerance. Integrative multi-omics data enable the identification of key candidate genes, biomarkers and regulatory networks, thereby allowing earlier and more precise selection in breeding programs. The adoption of omics-driven strategies is accelerating the genetic enhancement of the economically important traits, offering a comprehensive framework to improve animal productivity and health. Nevertheless, significant challenges remain, including constructing species and traits-specific omics databases, establishing robust correlations between omics-derived phenotypes and traditional traits, and translating omics discoveries into practical breeding solutions.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
