Example DNA Gramplet

The DNA Gramplet shows a DNA segment map as a graph.

Usage

You can install the DNA Gramplet on bottombar of one of the people category list views.

Create a DNA Association

To specify shared DNA segments between 2 people,

  • Create an Association for one person (Person A) with another Person (Person B) of the type DNA.
  • Create a Note in the Association of Type: "Association Note" with the shared DNA segment data.
    • The format of the Note is a comma separated list in the order: Chromosome Number, Start Segment, End Segment, flag for maternal/paternal side, shared length in cMs.
Flag for maternal/paternal side Description
M Maternal side
P Paternal side
U Unknown side


Sites like GEDmatch make this shared chromosome data available. There can be additional Associations between Person A and Person C et cetera as known. A sample set of data in one Note is shown below.

Example

Addon-DNA-Note-Example.png

Create an Association of type DNA as described in the Association page to Person A. Add a Note with the DNA shared segment data.


Addon-DNA-Association-Example.png

Save the Association.

Addon-DNA-Associations-Example.png

Add more associations as known. Each would be associated to a different person and have a different Note.

Addon-DNA-SegmentMap.png

Add the DNA gramplet to the Person view. Select the DNA tab. The segment map will be color coded by associated person. The P side is the top portion and the M side is the bottom portion for each chromosome. If the segment side is unknown, the segment will cover both the top and bottom portions of the chromosome and be 50% transparent.

Hovering the cursor over a known segment will pop up the name of the associated person and the length (in cMs) of the shared segment.
