Question 53

Essay

Among dogs,short hair is dominant to long hair and dark coat color is dominant to white (albino)coat color.Assume that these two coat traits are caused by independently segregating gene pairs.For each of the crosses given below,write the most probable genotype (or genotypes if more than one answer is possible)for the parents.It is important that you select a realistic symbol set and define each symbol below.
 Parental Phenotypes \text { Parental Phenotypes } \quad \quad \quad \quad \quad \quad \quad \quad  Phenotypes of Offspring \text { Phenotypes of Offspring }
