I was having a midday shower pondering a DNA conundrum, when I had a squirrel moment.
As most of you would know the degree of autosomal DNA shared between 2 individuals is a relevant measure.
Unless there's some hidden gem within Reunion that I've not encountered, there doesn't appear to be a structured method whereby this critical relationship between two individuals, ie. quantum of autosomal DNA, can be recorded. Perhaps the base infrastructure is already there by way of the Connections feature?? Or perhaps it goes hand in hand with the backend structure associated with the automatically calculated relationship between 2 individuals. You can probably tell by now I'm no software code cutter.
Right now I usually record the quantum of DNA shared between 2 individuals by copying the detail from Ancestry.com and pasting into an individual's Misc Notes field, or into a Source, eg.
Person 1 & Person 2
2nd cousin | Paternal side
4% shared DNA: 293 cM across 15 segments
A flow on from recording the cM measure between 2 individuals in a more structured format might open up the potential for all sorts of creative output, as in reports & charts.
Other considerations
1. I'm a fan of The Shared cM Project 4.0 tool v4. I know enough about the backend science to be dangerous but it's a terrific initiative and concept, and has real world practical use. However I don't contribute to the data because it requires manual input and as if I don't have enough to do already. HOWEVER, if this data was already captured within Reunion, and it was simply a matter of Reunion exposing a file in a format compatible for DNA Painter, does this not make sense? I imagine Leister Productions would need to collaborate with the folk at DNA Painter, but my guess is that wouldn't be difficult.
2. Off the bat I don't know whether the calculation of shared cM between 2 individuals is consistent between those making the calculation. I think I've noticed minor differences between say the output, as in amount of cM, calculated by Ancestry.con vs say GEDmatch. If it's an exact science with differences only due to perhaps rounding, then it's less of a consideration however if there are differences that flow due to differing techniques applied then a field for recording the source of the cM measure will also be relevant. The source is a requirement by the likes of DNA Painter anyway.
(For Leister Productions' consideration - I needed to edit the numbered list above and create a list manually instead. The numbered list function doesn't seem to work, though possibly a user issue.)
