Both Sides DNA

[HarrysMum]

Still none the wiser with D who is the closest of my shared matches. The other two are very distant so I’m ignoring them for the present.

One of my other three shared matched has a common ancestor on my mother’s side which is way back, not sure how she is related to my father.

My son is showing as being related to me on both sides and I have no idea how that can be true as I have found no crossover in the areas that my ancestors and those of my husband came from.

Lynn, if he matches you "on both sides", doesn't that mean your father's side and your mother's side.

His DNA match with his father won't show on your results.

My DNA match with my daughter is on both sides, i.e. she has DNA from both my parents.

Ah yes, that makes sense. Thanks

The smaller the match, the more distant the relationship. So it can be harder to work out where the smaller ones fit in. Phoenix at 8cms that could be an error.

There is also IBD vs IBS ie identical by descent vs identical by state. The first is obvious but the second one is just co-incidence. The smaller the match, the more likely it is IBS.

Libby I think the best way to work out your issue is to look at the dna through a chromosome browser, which ancestry does not have, to see where and how big the other side actually is.

How do I do that please?

If you have tested on ancestry you can't, unless you upload the raw dna to a different site like FTDna or myheritage. You would have to pay a small amount to use either of those sites.
