I. What types of alleles are GWAS analyses used to identify compared to Pedigree analyses?
A. GWAS: Weak, common alleles; Pedigrees: Strong, rare alleles
B. GWAS: Strong, rare alleles, Pedigrees: Weak, common alleles
C. GWAS: monogenic, Pedigrees: Polygenic
D. GWAS: nonsense, Pedigrees: Missense
E. GWAS: Missense, Pedigrees: nonsense
Homework Answers
Q1. Answer:Option B, GWAS: Strong, rare alleles, Pedigrees: Weak, common alleles.
Genome-wide association study (GWAS) is a genetic approach by which genetic variability is correlated with concern for a specific disorder.
GWAS analyzes used to classify the forms of allles relative to Pedigree analyzes.

Researchers examining families with hypercholestemia (high LDL levels) found missense alleles in PCSK9. While researches examining the genomes of individuals with very low LDL levels found nonsense allleles in PCSK9. I. How does PCSK9 regulate LDL levels? A. PCSK9 promotes LDL in the blood B. PCSK9 inhibits LDL level in the blood C. One cannot tell how PCSK9 affects LDL levels with just this information D. PCSK9 causes LDL levels to dramatically increase that then drop suddenly E. PCSK9 causes...
