The laboratory mouse is a small rodent commonly used in scientific research. Known for its genetic similarity to humans, it serves as a model organism in studies related to genetics, biology, and medicine. These mice are bred in controlled environments to ensure consistency in experiments. Laboratory mice are typically of the species Mus musculus and come in various strains, each with specific traits. They are used to test new drugs, study diseases, and understand biological processes. Their short lifespan and rapid reproduction make them ideal for long-term studies in a laboratory setting.
