NettetIn genomics, a genome-wide association study (GWA study, or GWAS), is an observational study of a genome-wide set of genetic variants in different individuals to see if any variant is associated with a trait. GWA studies … NettetThus, GWAS are often complementary to QTL mapping and, when conducted together, they mitigate each other’s limitations [10,11]. The basic approach in GWAS is to evaluate the associ-ation between each genotyped marker and a phenotype of interest that has been scored across a large number of individuals. This approach was pioneered nearly …
