X marks the Spot

Remember, all siblings will share some of their mother’s X chromosome. Only females will receive X chromosomes from their father, which is the entire chromosome they received from their mother. Males do not receive any X chromosomal DNA from their father, because the father gives them the Y chromosome. So, my brother shares the same maternal X chromosome donators that I do. However he has none of my father’s X donators. 

So each female has two initial donors, their mother and their paternal grandmother. If you use that basis when looking at your tree, you can easily identify which women were the donators in your ancestral line by identifying each donators mother and paternal grandmother.
Studies show that recombination in the X chromosome happens in an unusual manner. In that of your mother’s two X chromosomes, it is possible to for her to pass on one chromosome almost entirely intact. A 50/50 recombination of X chromosomes is not the norm. For this reason matches reflect deeper ancestry than the same match would on another chromosome in many cases.
