Hi- I read the previous X Inheritance thread(very interesting) and decided to check the X match between my son and my mother at 23andme. It was very surprising to see they have no matching segment at all. At gedmatch, after lowering the threshold to 1cM-100snps, their largest matching segment on X was 3.2cM-288snps. Total X match 16.8cMs.  Does this seem unusual, and does that mean my son's X-matches are all from my dad's side? My son and I share 196.1cM on the X. Rita

You passed your father's X-chromosome to your son with no or minimal recombination. In my extended family project the X-was passed through the mother intact about 20 to 25% of the time. My g-granddaughter had one of her X-chromosomes pass intact through both her grandmother and her mother. (She shares a full X-match with her gg-grandmother.

How much do you share with your mother? -----Original Message----- From: Rita Ruff via <genealogy-dna@rootsweb.com> To: GENEALOGY-DNA <GENEALOGY-DNA@rootsweb.com> Sent: Thu, Oct 15, 2015 3:55 pm Subject: [DNA] X-dna: Son shares none with maternal grandmother Hi- I read the previous X Inheritance thread(very interesting) and decided to check the X match between my son and my mother at 23andme.
