Using the data Table B, calculate the average number of kilobase (kb) pairs per centimorgan in the six multicellular eukaryotic organisms. How would this information influence strategies to clone genes known only by a mutant phenotype in these organisms?

Problem 21a
Textbook Question
Textbook QuestionApplied to the study of the human genome, a goal of GWAS is to locate chromosome regions that are likely to contain genes influencing the risk of disease. Specific genes can be identified in these regions, and particular mutant alleles that increase disease risk can be sequenced. To date, the identification of alleles that increase disease risk has occasionally led to a new therapeutic strategy, but more often the identification of disease alleles is the only outcome.
What personal or ethical issues arising from GWAS might be of concern to physicians or to those who might carry an allele that increases disease risk?
