Problem
There are two alleles for fur color in these mice. How many phenotypes for fur color are there in these mice? What does this tell you about the relationship between the two alleles?
I believe there are 3 phenotypes for fur color because there are dark brown, medium brown, and light brown mice. The Genotypes are Medium brown- RL RD, Dark brown is- RD RD, and light brown is RL RL. SO I'm not sure what this says about the relationship between the two alleles?
