Here's why:
* Biological similarity: Mice share about 90% of their genes with humans, making them a good model for studying human diseases.
* Small size and short lifespan: Mice are relatively small and have a short lifespan, making them cost-effective to house and breed.
* Reproductively prolific: Mice breed quickly and produce large litters, providing a consistent supply of subjects for research.
* Genetic manipulation: Mice are easily genetically engineered, allowing researchers to create models of specific diseases or conditions.
While mice are the most commonly used, other animals are also used in research, including rats, rabbits, guinea pigs, hamsters, dogs, cats, and primates. However, mice remain the most prominent due to the reasons listed above.
