The Mystery of Chromosome 17

by Eleonora Haas Published

The mystery has been solved by JD Cowell, a member of the Visual Phasing group on Facebook! All GEDmatch kits were deleted shortly after on August 2nd, 2022.

Number 17 happens to be my unlucky number, and once again it has proved to be just that.

When the DNA results of my father’s maternal half aunt V.P. arrived not that long ago, I was all over the moon. As a half aunt, she shares quite a bit of DNA with her nieces and nephews (on 20 out of 23 chromosomes!) and her results are incredibly valuable, because they point directly to their maternal grandfather. That amounts to gold, if you are a fan of the Visual Phasing technique.

This has raised several questions: Are there more? Where are they? How many of my previous Visual phasing results are incorrect because of hidden recombinations? Visual phasing is…

Last updated on July 19th, 2023. Today I accidentally stumbled upon the baptism record for Marie Lorgueil. She was born in Bordeaux on June 15th, 1634. The record was found by Gilles Brassard. (No, not the famous quantum physicist, but a fellow Québécois now living in Paris.) Last updated on Jan 27th, 2023. All sentences…

Visual Phasing of Chromosome 1 – updated version using Steven Fox’s Excel spreadsheet

If you have the possibility to test three full siblings, then the next great thing you could do with your DNA results is to try out the Visual Phasing technique developed by Kathy Johnston. It allows you to map the segments of your chromosomes to your four grandparents (without having them or your parents tested)…
