Recent work in Drosophila demonstrated that the genes known as the chromatin remodeling complex co-localize at loci for hsp genes that respond to heat shock. Outline a procedure you could use to substantiate this finding

A genome-wide association study (GWAS) can be used to tie the presence of a sequence variant of a DNA marker to a QTL influencing a specific phenotype. Thus, the relationship between an inherited genetic marker variant and the phenotype is by "association," which means organisms that carry a particular variant are more likely to have a certain phenotype than are organisms that carry a different variant. The assessment of association is quantitative; that is, it expresses the percentage of organisms with a genetic marker that also display a certain phenotype versus the percentage that have the phenotype but not the genetic marker. The advantage of GWAS over
other QTL mapping approaches is that GWAS can scan the entire genome for QTLs by statistically testing for markers. Thus, GWAS can be used to correlate known genes or SNPs with hsp loci.
