I have uploaded mine (F17298) and my mother's (F22508) Family Finder data (at-dna and x-dna) to GEDMatch.
A mystery to me is that I have far fewer matches on the x-chromosome than my mother and also have far smaller total cM (and largest segment cM) than my mother. A part from my match with my mother on the "X" - which is the expected 196 cM total - all of my x-dna matches are under 13 cM total and I have only about 20 matches where I share any x-dna at all.
My mother on the other hand has about 100 matches where she shares more than 30 cM of x-dna - she also has a highest shared x-dna of 81.7 cM (61.3 cM adjusted) with a largest segment of 17.1 cM for that match.
Cane someone please explain to me what is happening here?
