Genealogists, why do a genetic test?

It may seem unnecessary to do a genetic test, even though you have been studying your genealogy for many years. And yet you have forgotten an important element: this genealogy is declarative. Does it reflect reality? Evocation of 20 cases that make your genealogy not match reality.

Transfer your data to Myheritage.com

Update: Since the beginning of April 2018, MyHeritage has agreed to send DNA kits to France. French genetic genealogists cannot transfer their genetic data to MyHeritage.com.

Ethnicity results on 24Genetics

24Genetics proposes DNA sequencing that is particularly strong on ethnic origins. So I had to test it. So, I transferred my data from 23andMe (they also accept FamilyTree DNA data) and paid the 49 euros requested by the site. A week later I received a detailed report, presented below. Who [...]

Legalisation of DNA testing in France

In 2018, genetic testing for ethnic and genealogical purposes was carried out massively in France.

My opinion on MyHeritage's DNA test

After eleven years of genetic genealogy and as many genetic tests, I went straight to MyHeritage, the leader in DNA testing in France, when, in 2016, this start-up launched its first genetic tests.
