Thuto ea botsoalle e neng e pharalletse ea Gename (Gwas) e ikemiselitse ho khetholla liphaephe tsa liphatsa tsa lefutso (GeoTyPe) e amanang le litšobotsi tse ikhethang (Phenotype). Boithuto ba GWA Bareki ba liphatsa tsa lefutso ba beha granime e kholo ea batho ba bangata le batho ba ratang tlhahlobo ea lipalo maemong a lipalo. Ho tšoana le ganmenome ho ka utloisisa batho bohle ba liphatsa tsa lefutso. Ho kopanya ka data ea phenotytypic, Gwas e ka sebetsoa ho khetholla Snonotype Leano la Slaf ke ho ithuisa leano le thata la tatellano ea liketsahalo, le sibollang matšoao a ajoang a genomen, snp.
