The thing about me is that I'one thousand Jewish. It's non the simply thing well-nigh me. I'm also 5 feet xi inches tall, a spectacles wearer and into bicycling. But most people who know me probably wouldn't be surprised to acquire that most of my ancestors lived in shtetls in Eastern Europe.

So, information technology wasn't likewise surprising when I sent off 9 Deoxyribonucleic acid samples to three different DNA companies under a multifariousness of faux names, and the results indicated that I'one thousand super-duper Ashkenazi Jewish. (Ashkenazim are Jews who trace their ancestry back to Yiddish-speaking populations inhabiting the region between France and Russia.)

Here's what was a chip surprising, though: None of the companies — AncestryDNA, 23andMe and National Geographic, which works with a testing visitor chosen Helix — could concord on just how Ashkenazi I am. [How Do DNA Beginnings Tests Really Work?]

Iii companies, three errors and half dozen dissimilar results

AncestryDNA

AncestryDNA looked at the first Deoxyribonucleic acid sample that Live Science sent in for me and reported back that I'm 93 pct "European Jewish." The rest of my beginnings, it suggested, is as follows: two pct traces back to the Iberian Peninsula (that's Spain and Portugal); 1 percent traces dorsum to the "European South"; 1 percent traces dorsum to the Middle Eastward; and the rest comes from elsewhere.

The second sample produced similar — though, interestingly, non identical — results. This chip of Rafi-spit-in-a-tube, it reported, was just 92 per centum Ashkenazi, but a full three percent Iberian. The residue of the Dna, according to Beginnings, may have traced dorsum to the Middle East and European South or other regions. Just each of those sources accounted for, at most, less than ane percent of my Dna, according to the site.

(Live Science sent a tertiary sample of my DNA to Ancestry under a third proper name, only an error prevents u.s. from accessing the results.)

23andMe

Similar AncestryDNA, 23andMe concluded from the outset DNA sample that my Ashkenaziness ranks somewhere in the low 90s, with a smidge of difference between each of the samples it received. Unlike AncestryDNA, it had a non-entirely-Quondam World interpretation of where my ancestors may have come from — suggesting that perhaps a fraction of ane percent of my ancestors were Native American. (Given what I know of my family history, this is almost certainly not truthful.)

All the same, while I was reporting on this story, 23andMe updated its organization for interpreting Deoxyribonucleic acid samples and reassessed all the Dna already in its system. Now, when I log into 23andMe using the three different names I gave, the reports for two of those names say that I have 100 percent Ashkenazi ancestry.

(A third sample sent to 23andMe has returned no results. Alive Science assigned a woman's proper name to ane of the samples that it sent to each visitor and marked its sex activity as female. AncestryDNA candy its "female" sample merely fine, with no indication of anything unexpected, but both 23andMe and Nat Geo required more than personal information before proceeding, since it was from a person with unexpected chromosomes.)

Nat Geo and Helix

Finally, at that place'southward Nat Geo, which uses a service called Helix to do its DNA testing. Helix handles the raw Deoxyribonucleic acid processing, while Nat Geo handles the estimation.

Co-ordinate to Nat Geo, I'one thousand way less than 100 percent Ashkenazi. The genetic service reported that my kickoff sample's ancestry was 88 percent from the "Jewish Diaspora" (in this context, a term that more or less refers to Ashkenazim) and ten per centum from "Italy and Southern Europe."

Nat Geo too reported the biggest difference between its 2 successful samples, reporting that the 2d sample information technology received was three percent less "Jewish Diaspora" than the first — just 85 percent. The remainder, this fourth dimension, was 13 percent "Italy and Southern Europe."

So, nine DNA tests later, I learned this virtually myself: I'm a whole lot Ashkenazi Jewish. Like, generally. Or entirely. The rest of my ancestors in recent memory probably too lived in Europe — though who really knows where. And perchance somewhere in my family tree there was a Middle Easterner, or a Native American. Just probably (almost definitely) not.

Only, of course, I already knew all that.

The Scientific discipline

Scientists who specialize in this sort of research told Live Scientific discipline that none of this is all that surprising, though they noted that the fact that the companies couldn't even produce consequent results from samples taken from the aforementioned person was a bit weird.

"Ancestry itself is a funny affair, in that humans take never been these distinct groups of people," said Alexander Platt, an expert in population genetics at Temple University in Philadelphia. "Then, yous tin can't actually say that somebody is 92.half-dozen percentage descended from this group of people when that's not really a matter."

Log onto a website like Nat Geo's and it chunks the world up into different pieces. Some of your ancestors came from this spot, it says, and they were Primal Asian. Others came from that spot over at that place, and they were Center Eastern. But that'southward non what human history looks like. Populations fuzz together. People motility around, get together and dissever. A person who calls herself an Italian today might have called herself a Gaul a couple thou years ago and gone to war against the Romans.

To separate people into groups, Platt told Live Scientific discipline, researchers make decisions: For example, they'll say, the members of this group of people have all lived in Morocco for at least several generations, so nosotros'll add together their DNA to the reference libraries for Moroccans. And people who had 1 grandparent with that sort of DNA will hear that they're 25 percent Moroccan. But that boundary, Platt said, is fundamentally "imaginary."

"At that place is structure to history," he said. "Certain peoples are more than closely related to each other than to other peoples. And [commercial Deoxyribonucleic acid companies] are trying to create boundaries within those clusters. Only those boundaries never really existed, and they aren't real things."

In some places this is easier. Non-Jewish European populations, he said, tended not to mix quite as much with others as people elsewhere in the globe, so companies can hands depict finer distinctions between them.

But ultimately, it doesn't mean anything to be 35 per centum Irish, or 76 pct Finnish. So, when 23andMe changed its mind about my beginnings, the 100 per centum answer wasn't more than true. It was just some other way of interpreting the information.

(In this case, Platt said, the company probably decided that since but nigh all Ashkenazi Jews accept some genes in mutual with a mix of other European populations, it makes sense to call those genes Ashkenazi as well.)

"It'southward non really scientific discipline so much as it's description," he said. "There isn't really a right or wrong reply here, because there is no official designation of what information technology means to be Ashkenazi Jewish genetically."

It's not really weird to him that there's a 15 percent Jewishness gap between my results in Nat Geo and in 23andMe, he said.

Marker Stoneking, a population geneticist and group leader at the Max Planck Establish for Evoluntionary Anthropology in Leipzig, Germany, agreed.

"If they were to be completely honest, what they should tell yous is not that you're 47 pct Italian just that you're 47 plus or minus some error range … based on their ability to distinguish this ancestry and other sources of error that go into the estimation," Stoneking told Alive Scientific discipline.

And it's clear that there are sources of mistake, he said. Neither Stoneking nor Platt was sure exactly why AncestryDNA had a 1 per centum difference betwixt its results for different samples, or Nat Geo had a iii percent deviation, or 23andMe had wiggle room that disappeared with the update. But they agreed that it likely has something to do with their methods for converting a vial of spit into data for the estimator to interpret. (Alive Science asked all three companies to explain the issue, simply none gave a specific reply.) [Genetics: The Study of Heredity]

Each of these companies, Stoneking said, breaks down the Dna in the spit sample into alleles — genetic markers that they use as raw data. Only that process is imperfect and clearly doesn't work the same style every time the companies run the rests, he said — though the errors aren't hugely significant.

Should you get your DNA tested?

None of this means an ancestry kit from 23andMe or AncestryDNA or Nat Geo is worthless, Stoneking and Platt agreed.

"I view these things equally more for entertainment than anything else," Stoneking said.

The existent scientific discipline of population genetics, he explained, is used to figure out how large groups of people moved and mixed over time. And it's expert for that purpose. But figuring out whether three to thirteen percentage of my ancestors came from the Iberian Peninsula or Italia isn't part of that projection.

Platt said that he had gotten himself commercially tested, and that while he hadn't found anything surprising, it'southward always possible for someone to learn something new and interesting — particularly if they're of not-Jewish European ancestry and vague on the details. A white not-Jew might learn something specific and interesting virtually their background, considering their ancestors likely come up from highly isolated reference populations on which the companies have lots of data. But folks from other places have lower odds, but because the data from other places is more limited, fuzzy, and difficult to translate.

When I contacted the companies and asked them to comment on this story and to address the question of why my results may have differed — even when the exam was performed by the same visitor — both Beginnings and 23andMe responded.

Here's what Ancestry said:

"We're confident in the science and the results that we requite to customers. The consumer genomics industry is in its early stages but is growing fast and we tell customers throughout the experience that their results are as accurate as possible for where the science is today, and that information technology may evolve over fourth dimension equally the resolution of Dna estimates better[s]. We will e'er work to harness evolutions in science to enhance our customers' experience. For example, recent developments in Deoxyribonucleic acid science allowed u.s.a. to develop a new algorithm that determines customers' ethnic breakup with a higher degree of precision."

And here's the annotate from 23andMe, which the representative requested Live Science attribute to Robin Smith, a Ph.D. who holds the title of group project director at the visitor:

"Our ancestry reports are a living analysis and are ever-evolving, and every bit our database grows we will be able to provide customers with more than granular information near their ancestry and ethnicity. We are constantly making improvements to both our reference datasets, and the overall pipeline we use to compute customers' Ancestry Limerick reports. In fact, we recently rolled out a comprehensive beginnings update earlier in the yr, increasing the countries and regions nosotros report on — in society to provide more in-depth information to populations that are underrepresented in the study of genetics.

"In regards to the Ashkenazi reference populations, our precision for calling AJ [Ashkenazi Jewish] ancestry, has indeed improved from 97 percent to 99 percent over the by two years for these reasons. Our recall, meaning of all the Ashkenazi Jewish ancestry in the dataset, how much do we call AJ has improved to 97 percent, upwardly from 93 percent ii years ago.

"At that place may be inconsistencies across Deoxyribonucleic acid ancestry tests due to differing algorithms and reference panels that differ in key respects."

Nat Geo did not respond to multiple requests for comment by press fourth dimension.
