Adaptive evolution in humans has rarely been characterized for its whole set of components, i.e. selective pressure, adaptive phenotype, beneficial alleles and realized fitness differential. We combined approaches for detecting selective sweeps and polygenic adaptations and for mapping the genetic bases of physiological and fertility phenotypes in approximately 1000 indigenous ethnically Tibetan women from Nepal, adapted to high altitude. We performed genome-wide association analysis and tests for polygenic adaptations which showed evidence of positive selection for alleles associated with more pregnancies and live births and evidence of negative selection for those associated with higher offspring mortality. Lower hemoglobin level did not show clear evidence for polygenic adaptation, despite its strong association with an EPAS1 haplotype carrying selective sweep signals.
Tibetan Genotype data (high density)
PLINK formatted genotype data files (bed, bim, fam) for 344 unrelated Tibetan individuals genotyped on both the Illumina OmniExpress-24 v1.0 array and the Illumina HumanCore-12 v1.0A array. HumanCore array genotypes were used for markers found on both arrays.

Sherpa Genotype Data
PLINK formatted genotype data files (bed, bim, fam) for 103 Sherpa individuals, including genotypes from the Illumina OmniExpress-24 v1.0 array and for two separately genotyped SNPs in the EGLN1 gene.
