In a guinea pig, black is dominant to brown, and solid color is dominant to spotted. A heterozygous black, solid-colored pig is mated with a brown, spotted pig. The total offspring for several litters are black solid= 16, black spotted=5, brown solid=5, and brown spotted=14. If these genes are linked, how many map units are they apart?
