The advancements in second-/third-generation sequencing technologies, alongside computational innovations, have significantly enhanced our understanding of the genomic structure Y-chromosomes and their unique phylogenetic characteristics. These researches, despite challenges posed by lack population-scale databases, potential to revolutionize approach high-resolution, population-specific Y-chromosome panels databases for anthropological forensic applications. This study aimed develop highest-resolution Y-targeted panel, utilizing time-stamped, core informative mutations identified from high-coverage sequences YanHuang cohort. panel is intended provide a new tool complex pedigree search paternal biogeographical ancestry inference, as well explore general patterns fine-scale evolutionary history ethnolinguistically diverse Chinese populations. performance East Asian-specific Y-chromosomal including 2999-core SNP variants, was found be robust reliable. YHSeqY3000 designed capture genetic diversity lineages 3500 years ago, identifying 408 terminal 2097 individuals across 41 genetically geographically distinct We substructure that correlating with ancient population migrations expansions. New evidence provided extensive gene flow events between minority ethnic groups Han people, based on integrative Paternal Genomic Diversity Database. work successfully integrated Y-chromosome-related basic science translational applications, emphasizing necessity comprehensively characterizing genomically under-representative particularly important second phase medical or cohorts, where dense sampling strategies are employed.
