DNA triangulation app

Question

I have been using the DNA citation maker app for a while now. I have tried to do my first triangulation, entered the 3 WikiTree IDs, and then the source box does not have Ancestry as a DNA match source, as it does in the simple match section. Can anyone please shed light on this? Most of my matches come from ancestry.

Answer 1

Triangulation cannot be done using matches on Ancestry.com as they don't show chromosome segment details.  See https://www.wikitree.com/wiki/Help:Triangulation#AncestryDNA_Triangulation.  Triangulation can be done if all three testers upload their tests to sites like GEDmatch or MyHeritage.
