Workhorse representative species are those that are commonly used in scientific research, testing, or as model organisms due to their well-understood biology and genetics. These species are often chosen for their ease of handling, rapid reproduction rates, and ability to provide valuable insights into biological processes. Examples of workhorse representative species include the fruit fly Drosophila melanogaster, the roundworm Caenorhabditis elegans, and the mouse Mus musculus. These species have been instrumental in advancing our understanding of genetics, development, and disease. **
