Table 2 Human testis-enriched genes under positive selection detected in different human populations and genetic ancestries. Given are the SNPs with the highest iHS values, gene ontology (GO) terms and available QTL information (from the Genotype-Tissue Expression (GTX) database)

From: Population-specific, recent positive directional selection suggests adaptation of human male reproductive genes to different environmental conditions
