Final answer:
Scientists have found that the coat color in mice is determined by multiple genes influencing coat color, and not just a single gene. The presence of a separate gene at a different locus affects pigment production, and a mouse with a specific genotype is albino. Therefore, there is no correlation with coat color and a single gene determining coat color in mice.
Step-by-step explanation:
In mice, scientists have found that the coat color is determined by multiple genes influencing coat color. The mottled agouti coat color is dominant to a solid coloration, such as black or gray. Another gene at a separate locus is responsible for pigment production, and when a mouse has the homozygous recessive cc genotype, it is albino regardless of the allele present at the agouti locus. Therefore, the coat color in mice is influenced by multiple genes and not just a single gene.
