d) a and b

e) a and c

Homework Answers

Answer #1

Answer: Option D is correct.

Explanation:

Complex disorders are difficult to study as they are affected by both genetic and environmental factors. To study such disorders, we can perform QTL analysis and identify the potential candidate genes. These candidate genes can further be verified by GWAS (genome-wide association studies). The association studies will reveal whether a given candidate gene is the causative agent of the disorder in a given environmental condition.

In most cases, GWAS studies involve whole genome sequencing if the objective is to look for the SNPs at the DNA level.

A. If eradication of disease is the reason for the actions of the Eugenics movement leaders, their efforts would not be successful. Give two reasons why genetic diseases are difficult to eliminate. Hint: One reason is how genetic diseases arise (give specifics), and the other reason is the difficulty of identifying all individuals with the disease-generating allele especially if the disease is recessive (explain why identification is difficult). A third reason that it is not ethical to eradicate unfit traits...
