I am sure that was just a mistype. So the "X" that a woman would inherit from her father came from her paternal grandmother so it would not follow the male line backwards. curt mason wrote: > -From: "GD Wells" > -Subject: A Woman's DNA > -Please explain why a woman's DNA cannot be traced.

Daughters get one X from each parent. I don't think anyone knows how to tell which parent donated which X chromosome. It's known that it does make a difference, but it's not understood. The X is passed from father to son to son. Easy to track. Also, the Y test is cheaper than the X test. > > -I don't understand why not women - why only men?

Is that true?? > > The surname is irrelevant. Some are adopted, others may have been sired by the milkman instead of by their mother's husband. We can't tell by looking at the records. Some current studies of DNA lineages suggest that the 'milkman' may have been more popular than thought.
