Chromosome Mapping Tool Released

Aug3

The DNA segment chromosome mapping tool is now released for all to try. This is the current URL:

and the documentation is here:

Thanks to all the testers, I think the bugs have been found and fixed. The next release will have some enhancements so make your suggestions here. So far I expect to add the following features:

  • ignore the side column so alternately chose a side and color
  • better error reporting and more bullet proof
  • add a third option and thus line on the chromosomes for unknown or both
  • add a note column that is part of what appears on mouse over with the MRCA
  • allow selection of colors
  • make a version designed to show overlaps on unknown relatives

First version of Chromosome Mapping Tool

Jul31

I am looking for more testers and some feedback on the colors. Click the read more for more images. Yes my data has a small bug for chromosome 1 and 9 :). In the actual tool mousing over the color tells you the ancestor, the segment size, and start and stop points. The actual output is much larger than the image below.

Building a Color Coded Chromosome Mapping Tool

Jun22

I am starting work on a web based program that will generate color-coded images of the chromosome segments inherited from your ancestors on an image of all 23 of your chromosomes. Cece Moore has done this by hand and that is the model for what this program will do. Click here for the sample image  she posted in her geni.com blog article about autosomal DNA testing

The first release will just take your spreadsheet and make a picture. That spreadsheet will have the same columns as the family inheritance compare at 23andme (or chromosome compare at ftDNA and GEDmatch) plus 3 new columns, side (paternal or maternal), MRCA(s) and optional color choice for each MRCA. Initially 16 ancestors can be plotted. A color palette can be chosen instead of specific colors and that will include a grayscale for the color blind.

So I solicit all your suggestions. I am reposting here some of the thoughts of my fellow DNA-NEWBIE mailing list members, brought to us by ISOGG

We have results from a first cousin

May27

One of my cousins (half Norwegian) on Dad’s side (all Norwegian) just got his results. So I made this chart comparing myself to my 1st, 2nd, and 3rd cousins on Dad’s side. Mind you, the 2nd cousin is on Dad’s paternal side while the third cousin is on his mom’s side.

My brother’s chart looks very similar except no X match of course. Notice the very large X match I have with my first cousin which would come from his mother and my Dad’s mother, 57.3 cM. Interesting to see this as compared to my Dad ….

It’s a Match!! Lars Monsen’s ancestors are found.

May10

The direct male line descendant of Ole Monsen Titland  (1702-1764) is a Y-chromosome DNA 34/37 match to my Dad, who we thought was also a descendant of Ole. Now we know he is!

Thank you so much cousin Sigmund for finding a distant cousin in direct paternal descent to test.

This story was written up a few months back in a post here but we were waiting on the DNA Y-chromosome STR test to prove our theory. Now it is proven.

Here are the deeper details of the three markers that do not match:
