The results came out as half French, 40 % Spanish, some Italian, 1% Sardinian, 1% scottish-Irish. The major problem is that ancient Ibiza DNA has evolved to resemble that of modern French, same thing for Spanish-Valencian DNA: which is shared by modern French people. So if you do have French ancestry, it may show as Spanish and vice versa… THIS GOES FOR EVERYTHING ELSE: IT’S WILL BE VAGUE!
Specific tests for your father’s family include ‘Y-DNA’ tests which focus on the ‘Y chromosomes’ in your cells’ nuclei, passed down from father to son. Specific tests for your mother’s family include ‘mtDNA’ tests which report on a subset of DNA found in the ‘mitochondria’ (your cells’ energy factories), passed down from mother to son or to daughter.
There is one really, really important thing to know about this estimate, however. Each child inherits 50% of their DNA from each parent. That means that 50% of their parents’ DNA does NOT get passed down to the child. This can mean that a child of a 100% Eastern European person will only show 50% Eastern European DNA, and their grandchild will only show 25%, and their great-grandchild 12.5% – in a perfect scenario.
Guidelines recommend that women with a BRCA1 or BRCA2 variant should be screened for breast cancer earlier and more often. Risk-reducing surgery or medication may also be offered. Men with a variant should be screened for breast cancer. Screening guidelines for prostate cancer vary. This test is not a substitute for visits to a healthcare professional for recommended screenings. Results should be confirmed in a clinical setting before taking any medical action. It is important to talk with a healthcare professional before taking any medical action.
At-home paternity tests have been around much longer than other direct-to-consumer DNA tests. Most of them require you to collect cheek swab samples from a prospective father and child, which you then send off to a lab to determine paternity. For non-legal use, these tests can cost as little as $15, but tests that provide verified results that are admissible in court cost a few hundred dollars.
I was interested in the ethnicity test provided by African Ancestry because of their claim to be able to place your ancestry in a current African country or region. However after reading multiple reviews, I'm hesitant to spend $300 to find out my ancestors are "West African" or from Sub Sahara Africa. Is there any company whose test can place Ancestry within a specific region of African?
This is very interesting…thanks for sharing—regarding you husband’s results– the Somali 1% might not be so crazy at all—look at the map– horn of east Africa to Yemen area (had a large Jewish population long ago)…to Palestine-Israel…to Europe in the centuries long diaspora..actually your comments made me more inclined to try this newer company. I am grateful to you.
As it happens, most of the data on 23andMe seems harmless and fun. There are the “Neanderthal variants” (I have fewer of them than 58% of 23andMe customers, thank you very much), the bizarre earwax/earlobes-type data and, apparently, I have the muscle composition generally found in “elite athletes” (fancy). On the downside, my lineage isn’t as exotic as I’d hoped: 99.1% north-western Europe, of which 71% is British/Irish, with just 0.01% “Ashkenazi Jewish” to offset the genetic monotony. At £149, the 23andMe kit isn’t cheap and I’m quite tempted to demand a recount.
The 100,000 Genomes Project is an NHS initiative, run by Genomics England, and is the largest national genome sequencing project in the world. On entering, patients have their entire genome, of more than 3bn base pairs, sequenced. This is different from commercially available genetic testing kits, such as those from 23andMe, which only look at very small stretches of DNA in a process called genotyping. The hope of the NHS is that having so much genetic information, from so many different people, will allow “groundbreaking discoveries about how diseases work, who could be susceptible to them, how we can treat them, and what treatments might work”.
4. Geno 2.0: At $199 National Geographic’s Genographic Project is the most expensive of all of the choices and is also not deigned specifically for genealogists. They do not offer a database of known relations and the data they provide is more general in nature. However, joining the project does provide a geographic ancestry breakdown as well as a report on how much Neanderthal you may have (fun!). It is an exciting scientific endeavor and definitely worth exploring and joining if you have the resources to do so. Find it here.
