It's acknowledged that researchers rarely can perform direct experiments on human subjects. Therefore, model organisms become attractive examples to be studied when other species, especially humans, are not practical. Furthermore, a wealth of favorable characteristics also make model organism antibodies become a hot spot. Features of a Good Model Organism Since model organisms are vital tools for global scientists to study and reveal universal biological phenomena and laws, a preferred model organism should universally be: l Conducive to answering concerned research questions, and with physiological characteristics representing a large biological group. l Characterized with short generations, many offspring, easy to breed in the laboratory, and clear genetic background. l Easy to perform experimental operations, especially genetic manipulations and phenotypic analysis. To sum up, model organisms are typically chosen in terms of ...
