What is the main purpose of genome-wide association studies (GWAS)?

1. GWAS involve scanning the genomes of thousands of unrelated individuals with a particular skin colour and compare to other individuals.
2. GWAS involve scanning the genomes of thousands of unrelated individuals with a particular disease and compare with individuals who do not have the disease.
3. GWAS involve scanning the genomes of thousands of unrelated individuals with a particular mutation and compare with individuals who do not have the mutation.

How can information from GWAS be used to inform scientists and physicians about genetic diseases?

1. GWAS attempt to identify genes that influence disease risk.
2. GWAS attempt to identify genes that influence skin colour of individuals.
3. GWAS attempt to identify genes that influence mutation risk.
