Revealing close and distant relatives in ancient DNA with unprecedented precision

When screening ancient Eurasian individuals for IBD segments, the researchers detected a pair of biological relatives whose remains were buried 1,410 kilometers apart, one in central Mongolia and one in southern Russia. Credit: Nature Genetics (2023). DOI: 10.1038/s41588-023-01582-w

If two persons are biologically related, they share long stretches of DNA that they co-inherited from their recent common ancestor. These almost identically shared stretches of genomes are called IBD (“Identity by…
