T...I think you're focusing on the wrong column. The relative rankings are screwy because the total cM are screwy, which implies to me that FTDNA and GEDmatch have assigned significantly different cM scores to some of the places where you have matches. That first match is regarded as 72cM by FTDNA and less than half that by GEDmatch!<br /><br />As I understand it, both sites start with the same locations (and number of SNPs), but each has their own database of how likely each SNP is to mutate (which is how they map "number of matching SNPs" to "cM").Andrew M Greenehttps://www.blogger.com/profile/02999256144096980826noreply@blogger.comtag:blogger.com,1999:blog-6223435721248605051.post-48676281213016041142016-09-05T20:24:53.042+03:002016-09-05T20:24:53.042+03:00The problem is, Jim, that B, Joyce and Vladimir ha...The problem is, Jim, that B, Joyce and Vladimir have no confirmed relationships with anyone in the family. They all come from the same area, so they should confirm with each other but they don't. Same with Daphne, though her family is from someplace else.IsraelPhttps://www.blogger.com/profile/16748957039859625149noreply@blogger.comtag:blogger.com,1999:blog-6223435721248605051.post-41137241384141263192016-09-05T20:21:07.180+03:002016-09-05T20:21:07.180+03:00What would be interesting is if you could add a co...What would be interesting is if you could add a column to add the "Confirmed relationship". Then identify the relationship in the column. It might validate one or the other as giving a more likely relationship at least in the less than 4th and distant range. I guess it could grow some to add in the Ancestry kits on GEDMatch if any. Regardless, an interesting post.
