1. Discuss how incomplete penetrance, variable expressivity, pleiotropy, and genetic heterogeneity can affect the severity of a disease in a family.
2. A person can lower risk of preventable types of cardiovascular disease by exercising regularly and following a diet low in saturated fats and simple carbohydrates and high in fruits and vegetables. Why are these approaches ineffective against long QT syndrome?
3. Explain how the molecular bases of the various forms of long QT syndrome make genetic heterogeneity very likely
10. How incomplete penetrance, variable expressivity, pleiotropy, and genetic heterogeneity can affect the severity of a disease in a family.
In reference to incomplete penetrance the person that is experiencing a disease-causing genotype could possibly refrain from exhibiting the disease phenotype at all despite the capability of transmitting the disease causing mutation to the next generation. How this impacts the severity of the disease within the family has ...
View of technology advances on designer babies
As technology advances, the issue of "designer babies" and gene therapy seem to become a very real issue. In your opinion, do you think we should explore "modifying" genes? If so, in which cases?
What do you think about the implications for altering genes for health reasons (e.g., a genetic disorder) vs. altering genes for cosmetic reasons (e.g., to get a child with blue eyes)?View Full Posting Details
