Genome-Wide SNP Analysis Reveals the Genetic Diversity and Population Structure of the Domestic Reindeer Population ( Rangifer tarandus ) Inhabiting the Indigenous Tofalar Lands of Southern Siberia
Operating under the assumption that decline in population size increases the threat of loss of genetic diversity, herein, our first aim was to monitor and document the genetic diversity and population structure of the endemic Tuva–Tofalar reindeer, the number of which has seen a dramatic decrease.
