- In the accompanying pedigree, the vertical lines stand for protan color blindness, and the horizontal lines stand for deutan color blindness. These are separate conditions causing different misperceptions of colors; each is determined by a separate gene.a. Does the pedigree show any evidence that the genes are linked? b. If there is linkage, does the pedigree show any evidence of crossing over? Explain your answers to parts a and b with the aid of the diagram. c. Can you calculate a value for the recombination between these genes? Is this recombination by independent assortment or by crossing over?(picture added)arrow_forwardUse the pedigree below to answer the following questions about dimples. The dimple gene controls whether a person has dimples or doesn't have dimples. No dimples is dominant to dimples. 3 Dimples gene (D) No dimples is dominant to dimples 10 11 12 13 14 1.
