Mice range in color from white to light
brown, dark brown, silver, gray to black while some mice display
dual coloration. White and brown are the most common of these
combinations, while some specimens may have white, brown and
black coats. Colorful rodents are normally hamsters and gerbils.
However, there is no distinct species known as black mice.
Recent studies have shown that black coloration is dominant in
mutations. For these studies a male and female mouse were paired
in cages in combinations of white and white, white and black and
black and black.
