The Dalai Lama and some members of the Tibetan government subsequently fled to India, followed within a year by about 80,000 Tibetans. collected and generated the data, and performed the preliminary bioinformatic analyses to call SNPs and indels from the raw data. performed the majority of the population genetic analysis with some contributions from B.
