PSIV-6 The admixed history of Kola Peninsula semi-domestic reindeer population inferred from genome-wide SNP analysis.
Reindeer herding in Murmansk region (the Kola Peninsula, Russia) is based on the Nenets breed which replaced animals that were traditionally raised by Saami people in this territory at the end of 19(th) century. However, individuals representing the Kola Peninsula are morphologically different from...

Reindeer herding in Murmansk region (the Kola Peninsula, Russia) is based on the Nenets breed which replaced animals that were traditionally raised by Saami people in this territory at the end of 19(th) century. However, individuals representing the Kola Peninsula are morphologically different from Nenets breed being raised in Nenets Autonomous Okrug (NAO). Our study was aimed at investigation of genetic differences between two ecotypes of the breed. Using Bovine HD BeadChip, we examined 20 samples from Murmansk region (MUR) and 33 samples from NAO (NEN). Twenty-seven samples of wild reindeer representing Taimyr population were taken as an outgroup (WLD). Statistical analysis was performed using PLINK 1.9, Admixture 1.3, TreeMix 1.13 software and R packages “diveRsity” and “StAMMP”. 8781 polymorphic SNPs were selected for the analysis after the quality control. The analysis of population structure assigned semi-domestic and wild individuals to different clusters at K=2, which was determined as the best fit of our dataset. Herein MUR displayed admixture traces originating from WLD. The fact that MUR was an admixed population was confirmed by the f3 statistic (Z-score = -3.97, p-value < 0.001). TreeMix analysis revealed a migration event from WLD to MUR (p-value < 0.001). Pairwise Fst values between MUR and WLD (0.038) were lower than between NEN and WLD (0.061).
