8.  These companies are good at estimating the percentage of DNA at a
continental level
 Somewhat good at a regional level (e.g. Eastern Europe and Northern Europe)
 They are not so good at a sub-regional level (e.g. Britain and Ireland)
 They are also good at estimating percentages for endogmas groups
 They have difficulty with trace amounts of DNA. Trace amounts may be
significant or not?
 I found that the results can be around 5 percentage points off
 I would take results within that 5 percentage points with a grain of salt
 The ethnicity results may provide you with some information about your origins
you didn’t know or may not tell you anything you didn’t already know?
