Final answer:
An associated SNP is a single nucleotide polymorphism that is correlated with a certain trait or disease. It must show a significant statistical correlation with the trait or disease in order to be detectable in a GWAS.
Step-by-step explanation:
An associated SNP refers to a single nucleotide polymorphism that is detected to be linked or associated with a certain trait or disease in a genome-wide association study (GWAS). In order for an associated SNP to be detectable in a GWAS, there needs to be a significant statistical correlation between the SNP and the trait or disease being studied. This correlation indicates that the SNP may play a role in the development or susceptibility of the trait or disease.
