Hello List, I risk sounding a little stupid but where does all the DNA which isn't direct father-son-son-son or mother-daughter-daughter-daughter fit into these tests? It seems to me we all have either: XY for males XX for females each son would receive: Y from father X from mother each daughter X from mother and X from father What happens to the X DNA that women receive from their Dads? Why can that not be tested too? I'd like to know how much of my Gigha ancestry reached me! My gg-grandmother on my father's side was from the Isle of Gigha and I believe her father also was, whereas her mother was from Killean. Likewise my McKay ancestry from grand mother is reputed to be from the far north but that too is on my father's side. Apologies if I am too daft to understand! Mary Bigger. Stronger. Faster.

An individual's DNA does come from both parents after having undergone some shuffling. Constants, however, are the father-to-son yDNA and the mother-to-daughter mDNA. That makes these the only readily useful tools for parent-to-child lineage research. Some of the other DNA may help establish a population group, say, where a region is occupied mainly by people with certain physical characteristics. -----Original Message----- From: sct-islay-bounces@rootsweb.com [mailto:sct-islay-bounces@rootsweb.com] On Behalf Of em.paton86 via Sent: Thursday, November 26, 2015 11:23 AM To: J&K Herron; sct-islay@rootsweb.com Subject: Re: [SCT-ISLAY] DNA comparison with different testers
