What you can and can't learn from a DNA test. A nice article by Adam Rutherford in anticipation of the forthcoming programme on BBC Radio 4 on "The Business of Genetic Ancestry". I was interviewed for this programme. You can read more about it here: http://www.bbc.co.uk/programmes/b05vy4kb
The advent of cheap genetic sequencing has given birth to a burgeoning ancestry industry. But before you pay to spit in a tube, let me give you a few facts for free

The programme will focus on the positive aspects of DNA testing as well. It includes the inspirational story of Julia Bell who identified her mother's GI father through DNA testing. I believe this will be the first time that autosomal DNA testing has featured in the mainstream media in the UK. It's not DNA testing that's being criticised but the interpretation of the DNA results and specifically the silly haplogroup stories. Unfortunately the worst offender is a British company. Here is the latest story that appeared today: http://www.scotsman.com/lifestyle/heritage/vikings-still-running-rampant-in-scottish-dna-1-3781684 This is mild compared to some of the nonsense they've published in recent years. We've got a whole  website devoted to the whole saga with many more examples: https://www.ucl.ac.uk/mace-lab/genetic-ancestry Unfortunately when you have silly stories in the press and laughably bad programmes on TV it only serves to bring the whole field into disrepute. People buy expensive tests from thiscompany and are disappointed because they can't do anything with their results as there is no matching database.. Once they've paid out a lot of money to be told they're a Rhinelander or a Pretani it's then very difficult to persuade them that they have to pay more money to get another test done. This is the S4C programme on "Who are the Welsh?" which will be discussed in the radio  programme on Tuesday: http://cruwys.blogspot.co.uk/2015/03/more-on-s4c-dna-cymru-controversy-and.html There are also ethical issues involved about the misuse of public funds to promote an individual's commercial genetic ancestry business on public service TV channels. We've had the same problem when the BBC have been duped into promoting the company which is presented as a "research project" in disguise.

Dave Dowell compares his wife's admixture results with mine. His wife has largely Germanic ancestry and mine is all British. Guess who gets the highest percentages of "British" DNA?

A comparison of my admixture results from the three main genetic genealogy companies.
I have now taken an autosomal DNA cousin-matching test at all three testing companies – 23andMe, AncestryDNA and Family Tree DNA. With this type of test you also get as bonus feature a report of your admixture percentages. I ...

I shall look forward to your blog posts. There's a lot to be said about both the cousin-matching tests and the whole vexed subject of "ethnicity". There are a lot misconceptions flying around and it's very difficult to counter all the misleading information that gets disseminated so your contributions will be most helpful.

I'm on the radio next Tuesday. This should be a good programme.
A DNA test can help you find your long lost parents and allow you to build your family tree, but when it comes to our deep ancestry, the story is a lot more uncertain, despite what commercial testing companies may claim. Dr Adam Rutherford investigates what modern gene sequencing can (and can't) tell us with scientific certainty and identifies the hype and hyperbole from the often complex picture presented by modern gene sequencing At "the world'...

I've been meaning to write this blog post for some time but have only just got round to doing so. I've done a comparison of admixture results across three generations of my family. I was surprised at the amount of variation and my very English mum's very small percentage of "British" DNA. Only 7% of her DNA was "British"!
I wrote last week about comparing my admixture results from Ancestry, 23andMe and Family Tree DNA. At Family Tree DNA I have now tested three generations of my family so I thought it would be interesting to compare the MyOrig...

These criticisms did not stand up to scrutiny. See this response from Mendez et al in the European Journal of Human Genetics: http://www.nature.com/ejhg/journal/v23/n5/full/ejhg2014148a.html See in particular the supplementary material which includes a masterclass in population genetics.

Your readers might also like to know that some of the presentations from the DNA workshop at WDYTYA Live are being made available free of charge online: https://www.youtube.com/channel/UC7HQSiSkiy7ujlkgQER1FYw There are still some talks to be uploaded to the channel and in a few cases the speakers did not give permission for their talks to be recorded for copyright reasons. The workshop was sponsored by Family Tree DNA and the lecture shedule was organised by ISOGG.
In the US , when one thinks of WDYTYA, you think of the TV show. In the UK , besides there being a TV show, there is also an associated conference held called Who Do You Think You Are? Live. Since many of us have not nor will not ever attend this conference, it's great that select presentation ...
