Ancestry is offering its DNA Kit for just £49, the lowest we have seen it since Black Friday. The AncestryDNA kit usually costs £79, so you can save £30 with this offer, which is valid only this Boxing Day (December 26th).

AncestryDNA can estimate your origins to more than 1,000 regions around the world.

The company uses the DNA data to search its global network of 18 million AncestryDNA members to identify the people who share your DNA.

If you then sign up for the Ancestry family-history service, you can use the DNA results to help you when searching the billions of historical records and millions of family trees going back through many generations.

AncestryDNA utilises some of the latest autosomal testing technology. It analyses both the Y-chromosome and mitochondrial DNA.
