Maybe % of known relationships at each Gen number. e.g. Maybe 80% of all matches at Gen 2.0 have known relationships, but only 20% at Gen 3.0.<br /><br />I sent you by private email 3 relationships I know: an uncle (1.4), a 2C1R (3.6) and a 3C (3.7). <br /><br />At gen 1.4, I know the closest relationship of 100% of my matches. <br /><br />At gen 3.6, I know the closest relationship of 0.6% (1 out of 168) of my matches.<br /><br />At gen 3.7, I know the closest relationship of 0.2% (1 out of 444) of my matches.<br /><br />At all other gen levels, I know the closest relations of 0% of my matches.<br /><br />Thinking about this, I have hundreds of 3.6 and 3.7 matches I haven't identified relationships for. I find it hard to believe that they'll all be 2nd to 4th cousins, but expect they'll more likely be 3rd to 7th cousins at the closest, with other endogmatic (if that's a word) relationships at that level and further adding up to be a 3.6 or 3.7 equivalence.<br /><br />So I think your table (and Lara's cM table) are useful to figure out where known closest relationships should fall, but without further info we should be wary of using them as guides to what the closest relationship of an unknown 3.6 might be.<br /><br />LouisLouis Kesslerhttps://www.blogger.com/profile/11704667321407909489noreply@blogger.comtag:blogger.com,1999:blog-6223435721248605051.post-31198264437243834642018-04-18T05:07:15.857+03:002018-04-18T05:07:15.857+03:00As far as I know, she is doing an endogamous versi...As far as I know, she is doing an endogamous version of Shared cM.
