My DNA Football Team - Blog entry by lkessler - 11 Oct 2017
I was thinking about my 1 year old grand-nephew this morning, and how he and I would look to be half-sharing about a quarter of our DNA in a chromosome browser. Well that would make my grand-nephew the quarterback of my DNA Football team. His father, my nephew, would be the halfback. My daughters would be ...

Deep Ancestors - Blog comment by lkessler - 4 Oct 2017
Joe,
Sorry to take so long to respond. I hadn't seen Steven Fox's spreadsheet before. Couldn't find him or mention of his tool on Google. Finally, I discovered he was part of the Visual Phasing Facebook group. So I requested membership, and Blaine Bettinger, the group coordinator approved me. So finally I ...

Triangulation does NOT mean IBD - Blog comment by lkessler - 4 Oct 2017
Debbie: Well, I'm just looking at the results. And FamilyTreeDNA seems to have many fewer disprovals of IBD by parents at any given cM level than AncestryDNA does.

Triangulation does NOT mean IBD - Blog comment by lkessler - 3 Oct 2017
Very interesting, Debbie. So then it seems that FTDNA's criteria of at least one 9 cM segment is better (i.e. produces fewer false matches) than AncestryDNA's combination of phasing and inclusion of segments down to 6 cM. That may be indicative that AncestryDNA's phasing combined with its Timber may not be ...

Deep Ancestors - Blog comment by lkessler - 3 Oct 2017
Joe: I'm hoping to come up with a method of chromosome mapping using the match information and then display the map in the DMT output. If that is successful, then it will be an automated system that does what visual phasing does plus more (sometimes going back to generations further than grandparents). I think ...

Deep Ancestors - Blog entry by lkessler - 2 Oct 2017
In the DMT documentation on the Interpreting Results page, I have a section called Deep Ancestors. It says: If the Triangulated Group is from a common ancestor, then there may be smaller identifiable groups within it that are either from a later crossover down one descendant line (in which case all the ...

Triangulation does NOT mean IBD - Blog comment by lkessler - 27 Sep 2017
Debbie: I agree with everything you say (except maybe one thing, which I'll likely write about in a future blog post).
I was specifically talking about triangulation. Yes of course, a match between two people can be IBD. But the point of the article was to dispense with the notion that triangulation means ...
