Just for the record, as a geneticist, I don't see how anyone can claim to be "99.5%" anything. That's a problem with their science, right there. Sure, some alleles might be more common in some populations, but I think you'd be hard-pressed to be able to accurately define things in that way.
Peter, there could be some recombination between haplotypes to get 99.5%. At that low percentage, all it would take is a single chromosome exchange on one arm.
No, monogamy doesn't matter in this case. You personally are from a single lineage.
Whether you are biologically related to anyone in your family, well that's another story altogether...
I think the issues with regard to parentage are some of the most critical that 23andme are not dealing with properly. In some march of dimes birth defect studies - these are opt-in studies - as much as 15% of paternity is not confirmed by the DNA tests... My recommendation is to test you and your mom; and ask her honestly whether testing Dad is going to be an issue,,,
