K36 Ancestral Report sections regional estimation

In this part you can check your population estimations.

Oracles:

  - nMonte3

  - Admix4

  - Reference Points

  - Dodecad 2-Way


nMonte3 Oracle - gives very detailed frequencies  of your recent ancestry, and for people who are not from a mixed background. It also detects subtle regional differences.

nMonte3 with function pen=0, shows better distant admixtures for more individuals, or deeper ancestry, sometimes too exaggerated, so I prefer to standard nMonte3 in reports.

The big advantage of nMonte is the ability to make subsets of populations in a spreadsheet linked to your real "paper trail" ancestry. This is  called the targeted nMonte3 oracle.


Admix4 Oracle - is a different tool, similar to Gedmatch oracles, it compares your frequencies to the list of most similar averages (the same as the nMonte single item distances) or it models you as their combination (two-way, three-way or four-way). In some cases it is in line with combination of your real parents or grandparents ancestries


Reference Points Oracle - Similar to nMonte but uses different algorhit, putting more weight to genetic distances. It isn't used in case of very mixed peoples.


Dodecad 2-Way Oracle - The program considers all pairs of populations, and for each one of them calculates the minimum distance to the sample in consideration, and the admixture proportions that produce it; population pairs where the distance to one of the two populations is smaller than to any admixture of the two are ignored. Don't treat it as nMonte results, there are more theoretical combinations, showing your "shifts" towards for example more northern or more southern (or western / eastern) groups of populations.


Bear in mind that very closely related averages sometimes could show instead of your actual ones (i.e. Sw-England or FR_Britanny).
Also sometimes Jewish admixture could be masked by Sicilian or Greek Islander, or vice-versa.
