  E, Adults who have polycystic kidney disease have the AD type. So the dad I one of the allele 1,1 affected. so if kid III, 1 does not inherit that allele he does not have the disease

  Thank you.. but what can be said about 1,3. 1,3 seems like its a carrier in ROw I but not Row II? I'm confused...

  This is how I thought about it.

The question tells you that the child with question mark doesn't have the disease then what alleles would he most likely have. We know that APKD is a autosomal dominant disease so we look back at the father and we know that the 1 allele is the allele that expresses the disease because both his father and brother share at least one 1 allele. so if the son with the question mark doesnt have the disease at all, then he must have inherited the 3 from the father and 2 from the mother because she is 2,2.

dont be confused, the question is asking what alleles is the son a carrier for not that he must be a carrier of the disease because you cant be a carrier of a AD disease and not express it.

hope this helps!

  Wow..that does it!! Thank you so much!! I was dreaming of an AD scenario that wasn't phenotypical.. It's much more simple than that. Thanks again!
