Overview
Haplogroup R-Y134928 is a significant downstream branch under R-Y14051, representing one of the principal paternal lineages tied to early Inner Asian pastoral groups. Emerging during the transition from the Late Bronze Age to the Early Iron Age, Y134928 developed within steppe populations that maintained strong mobility across the Altai, Sayan and western Mongolian zones. Present-day carriers of Y134928 appear most frequently in northern China, Inner Mongolia, Xinjiang and portions of Mongolia, with additional presence in Kazakh and Siberian groups. This distribution suggests an origin associated with eastern steppe confederations that later interacted both culturally and biologically with Turkic and Mongolic speaking populations. Y134928's internal diversity indicates explosive demographic growth during the early medieval period, coinciding with historical expansions of Turkic and para-Turkic groups. Its deep rooted presence in northern China also implies incorporation into early state formations and multiethnic steppe-frontier societies.
