I'm trying to identify his father. I think if I run my grandmother's Lazarus kit with my mother, for example, I can at least isolate his DNA segments. However, then I need to go further and isolate his father's DNA segments, which I think I can really only do if I get enough cMs for a one-to-many kit for him (in part, by increasing my grandmother's Lazarus kit cM total and listing her as spouse). If I can get him to 1500, I can then run the "matches one or two kits" against the two children of his half brothers, and the larger segments should be his father's DNA. It sounds good in theory, at least!

The problem with further is you need relatives of that person who aren't descendants. And particularly when you're endogamous, any DNA you share with those 6th or so cousins may not even be from that common ancestor, so the kit isn't useful. I usually run Lazarus looking at reasonably large segments anyways (but one I realized things were weird, for this analysis I used their default values).Lara Diamondhttps://www.blogger.com/profile/01059622807880866607noreply@blogger.comtag:blogger.com,1999:blog-1011190131897264422.post-54359642646373370952017-05-21T09:38:03.924-04:002017-05-21T09:38:03.924-04:00That's no good!

Here's hoping Gedmatch is able to fix the problem. <br /><br />Prior to this discovery, had you ever used this tool to recreate the genome for more distant ancestors? I've been wondering if this would work for a 5th great-grandfather or if that's just too distant with autosomal DNA.Family Sleutherhttps://www.blogger.com/profile/11584864778317578299noreply@blogger.comtag:blogger.com,1999:blog-1011190131897264422.post-74169023411723961692017-05-21T00:07:34.204-04:002017-05-21T00:07:34.204-04:00Adding Aunt Betty to Group 1 runs MY total on the ...Adding Aunt Betty to Group 1 runs MY total on the problem chromosome to 108.8, but what's really odd is that it extends my match to 115,834,939 which is where A Betty's match with the other Group 2 member begins.IsraelPhttps://www.blogger.com/profile/16748957039859625149noreply@blogger.comtag:blogger.com,1999:blog-1011190131897264422.post-41899447456610482902017-05-20T22:46:11.083-04:002017-05-20T22:46:11.083-04:00I just did a one-on-one with the person in Group 2...I just did a one-on-one with the person in Group 2 with the problematic chromosome - he also shows 83.4 cM.IsraelPhttps://www.blogger.com/profile/16748957039859625149noreply@blogger.comtag:blogger.com,1999:blog-1011190131897264422.post-14925272238946811322017-05-20T22:37:21.738-04:002017-05-20T22:37:21.738-04:00OK, so I tried this using a very simple kit.

I put myself alone in Group 1 and a third cousin and a 3C1R in Group 2.<br /><br />The "Contributions" table showed nine segments (excluding chromosome 23). Then I did a one-on-one with me and the Lazarus kit. Everything came out right except one chromosome.<br /><br />"Contributions" shows two segments 8,963,653-59,890,187 (51 cM) and 82,425,667-90,201,144 (7.1 cM). That's a total of 58.1 cM.<br /><br />The one-to-one shows that chromosome as 8,966,210-90,188,979 (83.4 cM).<br /><br />This is obviously wrong.IsraelPhttps://www.blogger.com/profile/16748957039859625149noreply@blogger.com
