Within your family ancestry results we have provided three different views. This is because there is a degree of uncertainty about which populations make up your ancestry. With the views we add to your family ancestry results, we attempt to quantify this uncertainty within your family ancestry results, and strive to represent the uncertainties in our population assignment procedure as completely as possible.
COMPLETE (default view): In this view, we have attempted to assign all ancestry, allocating any 'unassigned' percentages (from your standard view) to regions to which they look most similar. In our attempt to be most complete about your assignments, we are forcing the algorithm to speculate and decide on where your unassigned percentages might go, and there will be more uncertainty associated with these assignments.
STANDARD: In this view, we highlight the sources of your ancestry which are likely to be present, using our best-guess of the exact source, within the limits of the 80 worldwide regions on which we can report. Ancestry that cannot be attributed to one of our reference populations is shown as being 'unassigned'.
CAUTIOUS: In this view, we have grouped the most genetically similar populations together. By being cautious and conservative about your assignments, we are most certain about these assignments of your ancestry breakdown. If you click on a region, and scroll down to its description, you will find some explanatory text. For example:
Southeast England-related ancestry
This is a confidence group* for Southeast England ancestry with small spread**. It includes Southeast England and South England populations. As it is the smallest possible grouping for Southeast England and surrounding ancestry, it is very likely that your true ancestry falls inside one or both of these two populations.
*Confidence groups are chosen so that we are confident that you have ancestry from at least one of the populations highlighted.
**Spread refers to the number of populations within the confidence group. A confidence group can be made up of 2 (small), 3 (medium), or 4 (large) similar populations.
This descriptive first paragraph will vary per confidence group and may vary per set of results; this means that your description of Southeast England-related ancestry (if you have it) may not be the same as another person's description of their Southeast England-related ancestry (if they have it).
These views are not available for motherline/fatherline results.
