Geneanet DNA has been launched 1 year ago. On this occasion, we are happy to announce a new and much-awaited option: the Chromosome Browser (Shared DNA segments)!
Click “DNA” then “View DNA matches” in the main menu bar, or click the following link: en.geneanet.org/dna/person/.
Click a DNA match and the Chromosome Browser (Shared DNA segments) will show up at the bottom of the page.
The human genome consists of 22 pairs of chromosomes (also called autosomes, numbered from 1 to 22) and 1 pair of sex chromosomes (also called heterosomes, identified by X and Y). Each pair of chromosomes contains a paternal copy and a maternal copy.
In the Chromosome Browser, each pair of chromosomes shows up as an horizontal bar which length depends on the total number of bases they contain. The Y chromosome does not show up in this chart because it is not used for the identification of shared DNA.
Each pair of chromosomes can contain up to 3 different pieces of information:
- The absence of shared DNA segment;
- The presence of a half-identical shared DNA segment, which means that the DNA you share with your relative is present on only one copy of the chromosome, thus inherited from only one of your parents;
- The presence of a full-identical shared DNA segment, which means that the DNA you share with your relative is present on both copies of the chromosome, thus inherited from both of your parents.
These additional information will help you to go further with your DNA relatives in particular, and with your genealogy research in general.
Please read our help page to learn more about it.
Good luck with your research!

Where can I find my DNA painter please?
Answer from Geneanet: Our chromosome browser is visible when you compare your DNA to a match – your common sections are highlighted (and you can export the data for use in DNA Painter, for example. See our help page on this topic for more information. Don’t forget our DNA forum is available for answers to your questions!

Can you download all your matches at once?

I was very excited to discover so many French matches, but with the addition of the chromosome browser it is apparent most are false due to the pile up region on chromosome 1.

I also have most of my dna matching segments in that region of chromosome 1.

So, how does one check this new feature if one already has loaded their raw DNA to your site? Is there a drop down hyper text for the users to click on that will show them the results of the bar DNA matchups? I would love to be able to utilize this new feature but am at a lost on how it works?
Patiently waiting,

Very happy that this function was added now! It also made obvious that many of my matches are not real because the matching segments are in a known pile-up region of chromosome 1. Maybe Geneanet could change their algorithm so these would be sorted out automatically. I think that happens on other sites.
