DNAprint Genomics (DNAG)

A57TBird - Do I understand you correctly?

You have a Great Grandmother who was 100% Native American, but your Ancestry results suggest that you are 100% Indo-European?

This re-opens a question that I proposed to the RB board some time ago. Since the evidence suggests that there is not a direct relationship between DNA heredity and genealogical ancestry, how then are the DNAP Ancestry results validated?

It is quite reasonable to presume that there is not a proportional distribution of genetic material from each ancestor. After all no one says that the baby has 'one fourth' of her grandmother's eyes. However, if such significantly statistical variations are commonplace, how were the results verified in the first place. If you test 100 people with a known ancestral record, and compare the results to their DNA ancestry as measured by DNAP, there must be a significant number of inconsistencies. How can these be resolved and still provide such a high degree of claimed accuracy?

Furthermore, if the results are subject to variations as extreme as the elimination of an ancestor as close as a Great Grandmother (one eigth of total ancestry) from the genetic record, how valuable will they be to Geneologists who are usually more interested in the 'historical' record than the physical?

Does anyone have any insight into this?
