Do you have Celtic or Viking DNA, or a mixture of both? How do you know this, and what are the main differences between these ancestries in general? Well in this video we will look at 5 key differences between Celtic & Viking DNA and how it relates to your genetics…
Now the first clue is in Signature Genetic Traits and Marker Alleles. Although this isn’t an exact science, these can sometimes offer clues to Celtic vs. Viking ancestry in an indirect way. Atlantic Celtic populations for example have the highest rates of natural red hair in the world, namely Scotland, Ireland and Wales, as you can see in this table.
While Vikings also sometimes had red hair, they showed higher frequencies of genes associated with blond hair, especially in Sweden. Now ancient DNA studies has revealed that Vikings exhibited a wide range of hair colors in general, yet blond hair was still elevated. So there is some truth to the idea of red haired Celtics and blond haired Vikings, yet there are many other variables involved as well that we will soon see. Certain diseases can also serve as clues. Hemochromatosis – which is an iron overload condition – is a good example of this. It is sometimes nicknamed the “Celtic curse,” due to its higher frequency in people of Irish or Scottish descent.
2. Y-DNA Haplogroups: The Strongest Signal
Now the second clue to Celtic or Viking ancestry is found in Y-DNA haplogroups, and this is one of the most powerful signals. And we also know the DNA markers of some of the most famous kings of Celtic countries in the past. So what do we know about Celtic vs Viking Y-DNA haplogroups then? Well the Y chromosome is passed almost unchanged from father to son, which allows geneticists to trace paternal lineages back thousands of years.
