5. Nicholas was born with albinism. So Theresa and Noah decided to meet with a
genetic counselor before having any more children to find out their odds for
having another child with albinism. The genetic counselor found out that Noah's
grandfather was also albino. His name was Nathaniel. Noah's dad, Niles was
normally pigmented and so was his mom, Nancy. Nathaniel was Nancy's dad.
Nancy's mom, Bridgit, had normal pigmentation. Add these people to your
pedigree by branching off of Nancy. How many total generations is your
pedigree?
