View Full Version : Question about resolution of ancestry composition

08-18-2013, 07:04 AM
Hey everyone,

I hope this in the right section, as I've just begun researching this.

I'm thinking about doing 23andme's ancestry composition test, specifically because I want to answer two questions: whether there is Chinese or European (Spanish?) blood on my mom's side (Filipino). The thing is, I'm not sure if this ancestry test (or any ancestry test) can get that specific. What do you think? Is there a different test or company I should try instead?

If it's relevant, I'm also half-Southern Indian from Kerala.

Thanks for any help!

I doubt it would be easy to pick up the difference between Chinese and Filipino heritage with Ancestry Composition, because there just aren't that many individuals with either ancestry in their database and there has been a fair bit of back-and-forth between the two places for hundreds of years.

But if you were to test your mother rather than yourself, it should pick up European ancestry if she has any, which should be subdivided into one of Northern or Southern or Eastern Europe, and if Southern Europe, this may be further broken down into Iberian.

In your case it could be especially important to test your mother instead of yourself because if you show Iberian ancestry, it could pertain to the time Portuguese were in Kerala rather than Spanish presence in the Philippines.

At the moment there's no (sub) resolution yet for East Asia but South Asia is already in its own category. 23andme promised they will start specifying East Asian as well as African ancestry in their upcoming update. But no idea when that will be. There's however some (free of charge) third party admixture tools you might want to use like on Ged-Match or analysis provided by Prof. McDonald. You just need to send them your "raw" DNA data, which is a file you can download on the 23andme website.

Impatient with 23andme breaking down the East Asian category there's been already two guys on 23andme who have developed their own calculators for specifying East Asian ancestry. You might want to check out these threads:

You might try one of GEDMATCH.com's many tools. Also it might be worth your while to try uploading to DNATribes as this may get some of the nuances you are after. Don't do their tests do the one that uses your already completed results.
