Ancestral origins

Using your deCODEme Genetic Scan results, we use a well-established computer program to match your chromosomes, segment by segment, to one of three different ancestral groups of humans - Africans, Europeans and East Asians. By doing this, we are virtually reconstructing the geographical distribution of your ancestors back hundreds and even thousands of generations.

Here, we provide separate estimates of ancestry for your 22 autosomal chromosomes and your X chromosome(s). While all your ancestors had an equal chance of contributing genetic material to your autosomal chromosomes, your X chromosome(s) were more likely to receive contributions from your female ancestors.

We also examine the ancestry of two very special parts of your genome, mitochondrial DNA (mtDNA) and the Y chromosome (carried only by men).
