Bridging precision agriculture and human medicine through comparative genetics.

Comparative genetics aims to resolve the genetic and molecular architecture of complex traits and the evolutionary constraints governing biology. Recent improvements in genome assembly, coupled with population-scale multi-omics, have generated high-resolution maps of genetic and functional variation across species. These advances have been particularly transformative for farmed animals, which have a rich reservoir of genetic diversity and provide an opportunity for systematic, full-lifespan, pan-tissue functional annotation not always possible for humans. Given the physiological similarities and shared selective environments between humans and farmed animals, a unified comparative framework that integrates human and animal omics data will enable a bidirectional flow of information and bridge the gap between statistical association and causal mechanism. This framework will be essential to accelerate the parallel development of precision agriculture and biomedicine.
