Which sophisticated technique was employed to model the genealogical history across the Hoiho genome?
Answer
Inference of Ancestral Recombination Graphs (ARGs).
Researchers utilized cutting-edge genomic analysis techniques, specifically the inference of Ancestral Recombination Graphs (ARGs), to model the entire genealogical history of the nearly 250 sampled individuals spread across the geographic range. ARGs are advanced models used to reconstruct the complex history of recombination events across an entire genome. By employing this method, scientists were able to uncover the deep genetic divisions, which indicated negligible ongoing migration between the Northern and Southern groups, thereby supporting the formal recognition of three distinct subspecies.
