Identification of Y-chromosomal Genetic Types for the Soldier's Remains from Huaihai Campaign / 法医学杂志

ABSTRACT

Objective To identify the Y-chromosomal genetic types for the soldier's remains from Huaihai Campaign,and to offer a clue for search of their paternal relatives.Methods DNA of the remains were extracted by the ancient DNA extraction method.Yfiler kit was used for the multiplex amplification of 17 Y-STR loci.The haplogroups of the samples were speculated.Detailed genotyping of the selected Y-SNP was performed based on the latest Y-chromosome phylogenetic tree.Haplotype-sharing analysis was done based on the data of Y-SNP and Y-STR,the closest modern individual information to the genetic relationship of remains was gained.Results A total of 8 Y-STR haplotypes were observed on 17 Y-STR loci of 8 male individuals.Furthermore,6 Y-SNP haplogroups were identified,which were O2a1-M95+,O1a1-P203+,O3*-M122+/M234-,D1-M15+,C3*-ST and R1a1-M17+.Conclusion Identification of Y-chromosomal genetic types for the soldier's remains from Huaihai Campaign shows a reference value on inferring the geographical origins of old materials.
