I did suggest to a scientific friend that it was POSSIBLE for a first cousin to have absolutely no common DNA. She said that in reality, you would actually have masses in common.


She is one of those people who makes you feel as if you have a very short genome

I agree with you, in that it would be possible, but it is unlikely to have no DNA in common. In fact it is possible for siblings to not have shared DNA but it would be extremely rare.

Toni, if you're testing both of your OH's parents then there's no need to test your OH as well, as far as family trees / DNA matches go, is there?

You have a point. Would I just need OH to do it? Same as for my side, Dad is happy to do the testing (and yet I'm still uncertain) but does he need to if I do it?

Or would having our parents do it be better? I have no idea if my inlaws would do it.

If both parents take DNA tests then you know which side of the tree any matches come from, whereas if it is their child who takes the test then the matches from both sides would be mixed in together. If the child and one parent take tests then you can tell which side a match comes from by seeing if it is a shared match or not.
