====== C57BL/6 mice ====== {{ ::c57bl6_mice.jpg?300|}} C57BL/6 [[mice]] are a common strain of laboratory [[mice]] that are widely used in research. They are known for their black coat color, which is caused by a mutation in the Agouti gene. C57BL/6 mice are used as a model organisms for many different fields of research, including genetics, immunology, neurobiology, and pharmacology. These mice have a number of advantages that make them popular for research. They are easy to breed and maintain, have a predictable genetic background, and are relatively resistant to many common diseases. In addition, their behavior and physiology have been extensively characterized, which makes them a useful tool for studying a wide range of biological processes. Overall, C57BL/6 mice are a valuable resource for scientists looking to understand the underlying mechanisms of various diseases and physiological processes.
