Separating Mother and Father's DNA


A distant relative has contacted me through a DNA match at this site. She is hoping to determine something about her father. She was adopted and does not know his name.

My question is this....

How does she separate out her father and Mother's DNA? Does she have to have a donor and triangulate (?) at Gedmatch?

That is how I was able to get a phasing kit for my deceased father and get the lines separated for myself.

Because I uploaded to this site using raw data from Ancestry.com, I do not know why she had to upload twice at Gedmatch using her raw data from this site.

Is her mother and father DNA already separated?

Can she determine if I am related to her Mother or Father?

I have determined through Gedmatch that she is related to me through my mother.

Any help is appreciated.

Well, if her mother is still alive and she tested her mother too, then it's easy to separate the two. Even if her mother isn't around to test, she might still be able to identify much of her mother's DNA by having close relatives of her mother test instead. Without knowing more about her situation, it's impossible to say whether she can determine if you're related to her mother or her father.

The way FTDNA's raw data is downloaded, you have to download one file for chromos 1-22 and then another file for the X chromo.
