DNA results are back!

[alphonsus123]

I also have my DNA results back, and rather surprising results they are. They read as follows. 97.9% Irish, Scottish and Welsh. 1.2% North African and 0.9% Nigerian. I myself was born in Greenore co Louth Ireland. Both my mother and father were born in Ireland as were my Grandparents, so where has the Nigerian connection and the North African connection come from? How accurate are these DNA results?

Considering that you got the vast majority as Irish, it seems pretty darned accurate in your case.

I don't know where you tested, but this article on Ancestry addresses how they handle such small percentages.  https://support.ancestry.com/s/article/Low-Confidence-Regions

These look like MyHeritage results.  I've noticed that quite a few Irish matches at MyHeritage have similar amounts of North African and Nigerian.

Interesting that your results are so wildly different from your brother's.

From my earlier link;

As a result of the random inheritance of DNA, close relatives can often be assigned markedly different ethnicity percentages.  This may be correct.  For example if you have three grandparents from Africa and one from Asia, you and your brother/sister may receive very different proportions of Asian DNA even though you share the same parents.  However such differences may also reflect inadequacies in the databases used, or the methods of inference applied.
