Diabetes researchers have long noticed that labs have different rates of success breeding mice to have the equivalent of Type 1 diabetes. At first, many scientists attributed this to poor management of genetic drift in some labs, but this theory didn’t hold up. If you transferred a group of mice from a lab with a lower rate of diabetes to a lab with a higher rate, the transferred group would soon exhibit the same rate of diabetes found in the new surroundings.
