Explanation:
Understanding through into genetic risk factors for various illnesses in the human population come from mouse research. Manipulation of the mouse genome is quite simple, for example, adding or deleting genes to better understand their function in the body.
The majority of mice and rats used throughout medical studies are inbred, which means they are genetically virtually similar, making the outcomes of medical trials more consistent.
Scientists study and track other animals' genes in an effort to understand how non-human creatures' genes work and operate. They do this to understand genetic risk factors in illnesses in the human population. This comes primarily from research on the genes of mice because mice are incredibly genetically close to humans --- there are literally thousands of genes in mice and rats that are phenomenally similar to humans. Manipulating their genes is extremely simple, such as adding or deleting genes to better understand their bodily functions --- also known as genetic engineering. The majority of mice and rats used in genetic research and medical studies are inbred and genetically similar, which makes the medical trial outcomes more consistent. This helps us find an understanding in whatever it is that we're trying to find.
