MG101: Molecular Genetics from SNPs to GWAS Overview

Play an AI-generated podcast conversation about this lesson

What is the main purpose of Genome Wide Association Studies (GWAS)?

To identify SNPs associated with diseases (correct)

To conduct case-control studies

To genotype up to 1X10^6 SNPs

To create a Manhattan plot

In a GWAS, what is the significance of SNPs found to be 'associated' with a disease?

They show frequency differences between cases and controls (correct)

They are not important for further study

They are unrelated to the disease

They cause the disease

What does a Manhattan plot represent in the context of GWAS?

Statistical significance of SNP associations (correct)

Association level based on gene function

Chromosomal order of SNPs on the X-axis

Genomic locations of SNPs on the Y-axis
