Coat color variation in mammals has long served as one of most fruitful examples

Question

Coat color variation in mammals has long served as one of most fruitful examples of genetics with over 120 loci and 800 alleles affecting coat color described in mice alone, For this, question, we will consider the adaptive transition from dark to light coat coloration that accompanied the movement of mice from the forest to the beach among two species of mouse. The ancestral species was darkly colored while the derived species was more lightly colored, consistent with the selective pressures that come when you are a dark mouse living on lightly colored sand. The phenotypes of the two parental species, along with a representative F1 individual and representatives from the F2 generation are shown below. Assume that you only had the data shown above for the parental lines (ancestral and derived species) and the F1. What inferences would you make about the mode of inheritance for the overall (whole body) coat color? Support your inferences clearly [do not just write the mode of inheritance, explain why vim armed at that answer). With the added data from the F2, what inferences might you make about the- mode of inheritance for the overall (whole body) coat color? Support your inferences clearly |do not just write the mode of inheritance, explain why you arrived at that answer].

Explanation / Answer

Multiple alleles are responsible for the coat color of mice. Multiple alleles doesnot just include 2 alleles but include more than two alleles responsible for the phenotype. Intemediate colors to the two parent colors are showed by the progeny. In multiple alleles there is a mix of types of dominance patterns that occur.
