There was also white rats with red eyes those were jumping like rabbits & they would bite me. Many investigators who wish to trace observations on behavior and physiology to underlying genes regard aspects of these in rats as more relevant to humans and easier to observe than in mice, giving impetus to the development of genetic research techniques applicable to rat. While the temple is home to over 25,000 black rats, just a few white rats are there. “Three Variations of Hairlessness Associated with Albinism in the Laboratory Rat.” Laboratory Animal Science, 1979.

The average litter size of the Sprague Dawley rat is 11.0. Yelliez. But occasionally they do secrete an organic compound called porphyrin from a gland near the eye called the Harderian gland. But rat experts say that albinism in rats is likely the first genetic mutation that was purposely bred by humans in domestic animals.
