Autosomal tests different servies linked to WikiTree - is it normal for the DNA "Test" results to be the same?

Question

I expected very similar results but not identical.

Answer 1

The match lists on the different sites will be different as they depend on who has tested at which site. Ethnicity estimates also use different algorithms and reference populations. There will be little difference in the raw DNA data.

Deb, Thanks for the best answer star.

Answer 2

I have seen identical kits analyzed by GEDmatch and MyH which produced similar, but not identical results ( 30.8cM & 24.2cM). However, Wikitree does not actually analyse the raw data. What you see here is a list of test takers who, IF their tree is accurate, should share some DNA with specific ancestors. Should a comparison on the site where the results are located does not show a match then there is a chance that you or the comparator has an inaccuracy in their tree, an NPE, etc.
