Different cM between mather & daughter matches
« on: Friday 31 July 20 23:30 BST (UK) »
Hi
I'm reposting my query as my original post seems to have been hijacked by another poster.

My husband has Ancestry DNA shared matches with a lady and her daughter.  The daughter shares more DNA with my husband than the mother does.  The mother shares 35 cM and the daughter 39 cM.
Would someone explain to me please how this can be?
Thank you

Not sure who ‘hijacked’ it, but here is a link to the other thread:

Thanks but I knew where the link was, but someone else replied to my query with a query of their own and the conversation went on with answers to their query and not mine.

I thought everyone was giving examples of similar anomalies with their own DNA matches.

There doesn’t seem to be a definitive answer as to how that sort of DNA variation happens.

Others might be able to offer further examples or explanations.  :)

They were but the replies were directed to pharma T's question and not mine.  Maybe that's how Roots Chat works, I don't use it that often.

All I can say kessa is that it happens.  On a couple of occasions my son has slightly higher matches than I do with a match.  In the scheme of things 4cM is nothing.

Janes - Keynsham and Bristol area.
Heale/Hale - Keynsham, Somerset
Vincent - Illogan/Redruth, Cornwall.  Moved to Sculcoates, Yorkshire; Grass Valley, California; Timaru, New Zealand and Victoria, Australia.
Williams somewhere in Wales - he kept moving
Ellis - Anglesey

For myself and my mothers dna it happens a few times at lower levels
The only match we have at a higher level where the son matches more than his mother is because his grandfather on his fathers side is also a match to our family .

That's what I thought from reading the original thread.

That's what I thought from reading the original thread.

The discussion on the original thread was targeted on establishing what might be the explanation of the DNA variation example quoted by Kessa.

This included various examples (including one of mine) which sought to help.

Please don't think, Kessa, that here we are in the habit of 'hijacking' threads for our own purposes.

It's just that I don't think we've been able to come to an answer, and unfortunately two threads about the subject might make the query more confusing.
