Genome-wide association study (GWAS) cholinga chake ndi kuzindikira mitundu yosiyanasiyana ya majini (genotype) yomwe imakhudzana ndi makhalidwe enaake (phenotype).Kafukufuku wa GWA amafufuza zolembera zamtundu wamtundu wonse wa anthu ambiri ndikulosera mayanjano a genotype-phenotype posanthula kuchuluka kwa anthu.Kubwereza kwamtundu wonse kumatha kupeza mitundu yonse ya ma genetic.Kuphatikizana ndi deta ya phenotypic, GWAS ikhoza kukonzedwa kuti izindikire ma SNP okhudzana ndi phenotype, QTLs ndi majini osankhidwa, omwe amathandizira kwambiri kuswana nyama / zomera zamakono.SLAF ndi njira yodzipangira yokha yosavuta yotsatirira ma genome, yomwe imapeza zolembera zamtundu uliwonse, SNP.Ma SNP awa, monga ma genetic markers, amatha kukonzedwa kuti agwirizane ndi zomwe akutsata.Ndi njira yotsika mtengo pozindikira zovuta zomwe zimagwirizanitsidwa ndi kusiyanasiyana kwa ma genetic.
