What are organisms that are extensively studied to compare results across different species known as?

• A. Gene banks
• B. Model organisms
• C. Experimental subjects
• D. Control groups

Answer: (B)

The term for organisms that are extensively studied to compare results across different species is "model organisms." These organisms are selected because they have certain advantageous characteristics that make them suitable for scientific research. Model organisms often include species that have a short generation time, a well-mapped genome, and the ability to be easily manipulated in a laboratory setting, such as fruit flies (Drosophila melanogaster), nematodes (Caenorhabditis elegans), or mice (Mus musculus).

The use of model organisms allows researchers to gain insights that can be generalized to more complex organisms, including humans. By studying these species, scientists can explore fundamental biological processes, basic genetic principles, and various disease mechanisms, making model organisms invaluable to genetics and biomedical research. This comparative approach is essential for understanding evolutionary relationships and applying findings across different biological systems.
