Construct a pedigree of the families in 6) and (C). Assume that one of the normal
children in (b) and one of the albino children in (c) become the parents of eight children.
Add these children into the pedigree, predicting their phenotypes (normal or albino).
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)
