Mice are preferred for experiments due to their rapid breeding, small size, and genetic similarity to humans, making them suitable for studying diseases and testing treatments. Toads and frogs have limited use in research, with amphibians primarily utilized for dissection in education and specific toxicological studies. The decline of certain amphibian species also raises ethical concerns regarding their use in research.
Mice are preferred in experiments because they are genetically similar to humans, have well-established research protocols, and are easier to breed and house compared to toads.
