‘Why has my ethnicity estimate changed?’

If you have an AncestryDNA test you may have noticed there has been an update to ethnicity results. If you haven’t already done so, pop across to the DNA story on your DNA home page and see what happens! So, what has Ancestry done and what does it mean for us? Karen Evans explains

Firstly, I want to stress that your DNA hasn’t changed or been altered in any way, the change is the ‘tools’ Ancestry uses to analyse it. I tried to think of an analogy which helped me to understand what it is that Ancestry has updated.

I’m imagining when we sent Ancestry a DNA sample in the past its experts looked at it with a magnifying glass and, using what they saw and based on their other samples too, they told us that our sample had an awful lot of similarities to other samples from particular places (reference samples). This gave our ethnicity estimate. With the update they have taken another look at your sample with a microscope rather than a magnifying glass and can see a lot more. They have also looked at everyone else’s samples and, using all the new things they can see, decided what samples you are now most like.
