The last two Chromosomes (13 and 14) went well. We will see what is in store for Chromosome 15. Actually, I see that I have been working on Chromosome 16, so I’ll go with that.<\/p>\n

Chromosome 16<\/h2>\n

After a break with the two easy Chromosomes, it looks like I am back to a bit of a challenge:<\/p>\n

\"\"<\/a><\/p>\n

I have two difficult areas, signified by lack of siblings’ initials.<\/p>\n

Cousin Matches – the Easy Way Out<\/h2>\n

It is my hope that cousin matches will define some of the confusing crossover areas. I’ll start with Hartley cousin Maury:<\/p>\n

\"\"<\/a><\/p>\n

Maury shows that Jim has a crossover at 72.3 in the second problem area.<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

Once I saw that crossover, it appeared that there was only one other crossover (for S). This is what I get:<\/p>\n

\"\"<\/a><\/p>\n

Back to Maury<\/h3>\n

\"\"<\/a><\/p>\n

That is what I get out of Maury’s match. I note that the end of Maury’s first match with Lori is at 20.1M and the end of the other matches is at 21.1, so there is a possible crossover for Lori there. I’ll hold off on that for now until I find other information.<\/p>\n

Matches with Rathfelder cousin Anita fill in some maternal DNA:<\/p>\n

\"\"<\/a><\/p>\n

Matches with Lentz cousin Joan give the other side of the maternal coin:<\/p>\n

\"\"<\/a><\/p>\n

Figuring Out the Two Missing Crossovers with a Detailed Analysis<\/h3>\n

The first step is to look at the V & H comparison at Gedmatch full resolution:<\/p>\n

\"\"<\/a><\/p>\n

This gives the positions of the crossovers at 20.4 and 21.6.<\/p>\n

The V & L comparison has two very close changes:<\/p>\n

\"\"<\/a><\/p>\n

This is because Jim (V) and Lori go from NIR and quickly to an FIR with a small FIR in the middle.<\/p>\n

Here are the results:<\/p>\n

\"\"<\/a><\/p>\n

The FD and DL are for the crossover for Joel (D) that I already have. I interpret the other matches to mean that there is a close double crossover for Jim (V). One is at 20.3 and the other is at about 21M.<\/p>\n

Expanding Around the Double V Crossover<\/h2>\n

My next strategy is to work around Jim (V). This is because I’m not totally sure of the two crossovers.<\/p>\n

\"\"<\/a><\/p>\n

I’ll use the gedmatch sibling comparisons to expand the DNA more:<\/p>\n

\"\"<\/a><\/p>\n

At this point, I see that Jim (V) and Heidi are NIR in the larger missing segment above. That means that Jim needs to be Hartley \/Rathfelder\u00a0there which agrees with the proposed double crossover for Jim (V).<\/p>\n

\"\"<\/a><\/p>\n

I don’t know how to fill in the little V-V segment. This would have to be either Frazer\/Rathfelder or Hartley\/Lentz. If it was Hartley\/Lentz, then Jim would be FIR with Jon, Joel and Sharon in that little segment.<\/p>\n

Here is Jim and Jon:<\/p>\n

\"\"<\/a><\/p>\n

Here’s Jim and Joel:<\/p>\n

\"\"<\/a><\/p>\n

Here’s JIma and Sharon:<\/p>\n

\"\"<\/a><\/p>\n

The question is: Is there a FIR between about 20.8 and 21.2M? I can’t tell, but I’ll say there is:<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

Basically, it is not a big deal either way, so it’s a judgement call.<\/p>\n

Here’s my crossover list:<\/p>\n

\"\"<\/a><\/p>\n

After working the DNA a bit, I get this:<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a><\/p>\n

This comparison between the Segment Map and the Gedmatch sibling chart confirms Chromosome 16<\/p>\n
