When you look at this pedigree, what could have caused an affected grandchild to appear even though there is no history of affected ancestors?

What is:
A mutation in the kid's DNA. It causes the alleles to change.
This occurs because of inbreeding. There is a higher chance of mutations if you mate within your immediate family.
