Answer:
The mouse is one of the most commonly used animal models. Mice have a high genetic resemblance to humans and a short reproductive cycle, making them excellent for genetics, drug screening, and illness modeling. They've helped us grasp human diseases including cancer, diabetes, and neurological disorders. Furthermore, mice can be genetically changed to imitate specific human genetic disorders, allowing researchers to investigate the consequences of these abnormalities.
Nonhuman primates, such as monkeys, are important models for researching complex behaviors, cognitive processes, and infectious diseases. Their human-like genetics and excellent cognitive abilities make them essential in understanding human brain problems and creating therapies. However, because of ethical concerns and high expenses connected with primate research, their use is limited to select fields of study.
The zebrafish is another useful animal model. Zebrafish embryos are transparent, allowing researchers to see developmental processes in real-time. They are frequently employed in developmental biology research, toxicological screening, and medication development. Observing organ growth and regeneration in zebrafish provides important insights into human biology.
Computational models have grown in popularity in the realm of simulation. While not classic animal models, these simulations utilize mathematical algorithms to mimic biological processes. They offer a less expensive and more ethical alternative to animal testing, particularly in drug development, virtual screening, and predictive toxicology.
