Females inherit TWO X chromosomes -- one from their mother and the other from their father. Normally, taken alone, I'd not be able to tell which was which--but this match has to be with my dad's X because my mother's wouldn't have matched his from his mother because our relationship is provable through my dad and his mother. His mother had TWO X chromosome as all females do--but she would only pass one along to her son or daughter and the father would contribute the other -- an X or a Y depending upon the sex of the child. (There are some rare males who inherit an extra X and are XXY but that is very rare and, don't laugh, has been associated with a proclivity for being a mass murderer--for real, I'm not making this up). </DIV> <DIV> </DIV> <DIV>Joan</DIV> <DIV class=im> <DIV> </DIV> <DIV> <DIV>In a message dated 10/29/2009 7:00:35 P.M.
