DNA Gene Mapping confusing question

Hi there Im referring to Chapter 5 Gene Mapping in the Genetics section. For question 5 at the backside in the answers and explanations, the answer is right and I agree with it but the explanation is confusing, it says that all the individuals from 2-6 are recombinants between these loci of ABO and MN, and that individuals 3-7 are recombinants between the disease and MN. How is this possible? from my deduction only 3 4 5 and 7 are recombinant between ABO and MN, and 3 4 5 7 are recombinant between disease and MN allele. Please explain this :/

Yes that is the only question which doesn't make sense and I'm almost sure the explanation is wrong. If you are being able to do all the other similar questions in the book you're fine. Don't worry about this one.

This topic isn't considered too high yield is it? I think from all the nbme questions I've done, which is at 2,200 I've probably we this come up 2 to 3 times. A couple in the older offline nbmes and one in the newer nbme exams, which we have to purchase.
