Flag question: Question 1

Question 1 1 pts

What best describes the focus of population genetics?

Group of answer choices

Evolutionary changes in population allele frequencies

Evolutionary changes in population genotype frequencies

Allele and genotype frequencies within populations

Allele and genotype differences between individuals

Flag question: Question 2

Question 2 1 pts

What two genetically-determinable quantities does the Hardy Weinberg equilibrium relate?

Group of answer choices

Phenotype prevalence within populations

Genotype and phenotype frequencies

Allele and phenotype frequencies

Allele and genotype frequencies

Flag question: Question 3

Question 3 1 pts

If the frequency of alleles “a” and “A” within a population are 30% and 70% respectively, what are the the expected Hardy Weinberg frequencies of various possible genotypes?

Group of answer choices

aa = 9% AA = 49% aA = 42%

aa = 28% AA = 30% aA = 42%

aa = 9% AA = 42% aA = 49%

aa = 49% AA = 9% aA = 42%

Flag question: Question 4

Question 4 1 pts

How might the Hardy Weinberg relationship be used to evaluate a new SNP genotyping technology using multiple individuals from a population?

Group of answer choices

If genotypes match the reference genome, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs.

If observed phenotypes follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs.

If genotypes and allele frequencies follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs.

None of the above

Flag question: Question 5

Question 5 1 pts

What best describes the focus of Pharmacogenomics?

Group of answer choices

Relationships between metabolism of pharmaceuticals and genetic pathways.

Relationships between therapeutic effectiveness of pharmaceuticals and genomic makeup of individuals.

Pharmaceutical side effects, personalized medicine, and genetic testing of patients.

Genomics and genetics of disease-causing mutations and the search for effective medicine to remedy these.

Flag question: Question 6

Question 6 1 pts

Why might a pharmaceutical company restrict the ethnicity of patients participating in a medical trial or, better yet, require patient genotype data (hint: population genetics of drug metabolizing enzymes, receptor isoforms, etc)?

Group of answer choices

To sample genetic variation and identify more adverse drug responses.

To increase potential genetic variation and (hopefully) obtain more clear-cut results.

To reduce potential genetic variation and (hopefully) obtain more clear-cut results.

There is no generally valid reason to do this.

Flag question: Question 7

Question 7 1 pts

What best describes the “1000 genomes” project?

Group of answer choices

A project intended to demonstrate that 1000 genomes can sufficently represent human variation.

A long-runing project described as “A deep catalog of human genetic variation”

A project aimed at getting the cost of medical sequencing down to a managable level.

None of the above

Flag question: Question 8

Question 8 1 pts

What is NOT true of “exome” sequencing as compared to whole genome sequencing?

Group of answer choices

Exome sequencing is cheaper.

All protein coding genes are covered.

Covers approximately 10% of the genome.

Can miss important genomic features (like regulatory regions, RNA-genes, etc).
