I think you mean Gil, not Zach? [EDIT: oh, wait, I see now it was Zach pushing for the test, that's what you meant.] Also, if Gil and Zach have the same father, they'd share a Y chromosome and hence a paternal haplogroup, whereas if Gil were the child of LW and some boyfriend, it would be way less likely (though not impossible) that he would have the same paternal haplogroup as Zach. Assuming Zach and LW are indeed full siblings, they would have their mother's maternal haplogroup, so that wouldn't be a point of distinction between LW's mom and LW as mothers. But if Zach was Gil's father and the mother was his girlfriend, again it would be unlikely for LW's maternal haplogroup to match the girlfriend's.
