Question: Can you determine all of the genotypes in this pedigree with certainty? why or why not?

thanks! and please provide the genotypes!!

I dont believe you can,
the third generation married couple both are carriers for the disease, that is why they had a child with the full dieases. Also, one of the parent of the second generation is also a carrier, but i cant determin which one it is.

There isnt enough information on the pedigree to determine every genotype.
