I understand this just now. Does this work the same for females and their fathers? I mean do the X and Y recombine into a new X Or do females inherit their X strictly intact from their fathers -----Original Message----- From: Paul Rakow via <genealogy-dna@rootsweb.com> To: genealogy-dna <genealogy-dna@rootsweb.com> Sent: Wed, Oct 14, 2015 12:16 pm Subject: Re: [DNA] X-inheritence W, Your mother, being a woman, has two X chromosomes, you (male) have just one. All of your X chromosome will match your mother, but quite possibly, parts of it will match her on one of the Xs, and parts on the other. But any place on your X chromosome only matches to one of your mother's two X chromosomes. The match between your mother and her cousin must be on the X chromosome that you don't match, at that region. I don't think you can be sure that you have an intact chromosome from your mother - one end of your X chromosome might match to the X chromosome your mother inherited from her mother, and the other end might match to the X chromosome your mother inherited from her father, and you would still show a perfect match to your mother over the whole length of your X chromosome.

Will, For all practical purposes, the X a woman inherits from her father will be intact, while the X from her mother might be recombined. Fine print: there is a little bit near one end where the X and Y chromosomes are similar, and it is possible for DNA to cross over. But we don't normally worry about that.

So when looking at the X-any way to determine WHOSE X it might be???? Its the one from mom or the one from dad ?? In a male or in a female...very confusing.

Actually, because the X comes intact from father to daughter, the whole thing is a little less confusing than all the other chromosomes!

So if a father matches on the X to some cousin for say 20cms, the daughter should match *exactly* the same to that cousin Is that correct? -----Original Message----- From: Paul Rakow <paul.rakow@cantab.net> To: Wjhonson <wjhonson@aol.com> Cc: genealogy-dna <genealogy-dna@rootsweb.com> Sent: Wed, Oct 14, 2015 12:41 pm Subject: Re: [DNA] X-inheritence Will, For all practical purposes, the X a woman inherits from her father will be intact, while the X from her mother might be recombined.
