The haplotype frequencies can be sensibly reported in groups of spatially distributed populations (Metapopulations) sharing a common ancestry and thus a similar pool of deep-rooting lineages. To describe the hierarchy of metapopulations we use a knowledge-based terminology, which incorporates linguistic, geographical and genetic resources, e.g. Eurasian-European–Western European or East Asian-Korean (see Willuweit S., Roewer L. (2015), ‘The new Y Chromosome Haplotype Reference Database.’, Forensic Sci Int Genet 15, 43-8 [Pubmed] [DOI]).
