Randomized trial analyzes Y-haplogroups in indigenous populations, revealing significant genetic shifts over time.

The research aims to compare the Y-chromosome data of ancient Scytho-Siberian populations with modern Tuvan populations.
Analyzed Y-SNPs and Y-STRs of ancient Y-chromosomes and modern Tuvan samples.
Conducted phylogenetic network analysis integrating data from both ancient and modern specimens.
Sample size included 633 modern Tuvan individuals.
Haplogroups Q and R1a frequencies dropped from 85% in Scytho-Siberians to 35% in modern Tuvans.
Dominant modern haplogroups include N-P43, N-M178, and O-M175, absent in ancient samples.
Young TMRCA estimates for modern Q-YP1102 and R1a clusters suggest recent lineage divergence.

Adamov et al. (2026) studied this question.
