Genome-wide associations studies (GWAS) are used to identify
genetic variants, such as single-nucleotide polymorphisms (SNPs),
that are associated with specific disorders. GWAS analyses compare
the genomes of individuals with a disorder to those without the
disorder. Which of the following factors are critical to GWAS
design? Select all of the statements that apply.
Good quality control is essential for identifying SNPs associated with a specific disorder Replication of sampling and sample analysis are important for verifying SNP association with a...

Explain the difference between the concept of the traditional use of the word “genetic mutation” and the more contemporary term “genetic variant”. Explain the concepts of 1) harmful mutations and purifying selection, 2) of neutral mutations and 3) variants that are retained via positive (or Darwinian) selection. Explain how a positive variant may influence local alleles (on the same chromosome very close to the new positive variant) by selective sweep of hitchhiker alleles.

hypertension, in what other ways may this information be used to
inform the management of his disease?
Frank Smith: Application Mr. Smith has a prior history of hypertension for which he does not currently have the necessary prescriptions. A nursing assessment needs to include dietary considerations along with questions about the availability of his healthcare provider and financial status.
