Question

Describe two of the applications for genome mapping.; Identify a possible advantage and a possible disadvantage of a genetic test that would identify genes in individuals that increase their probability of having Alzheimer's disease later in life.

Answer 1

Genome mapping has various applications, including the identification of disease-causing genes and environmental benefits like pollutant clean-up, as well as improving crop yields. Genetic testing for Alzheimer's risks can be both empowering and stressful.

Step-by-step explanation:

Two applications for genome mapping are (1) it aids in identifying human disease-causing genes and thus contributes to understanding and treating conditions like cancer, heart disease, and cystic fibrosis, and (2) it supports efforts in environmental science, such as the development of microbes that can clean up pollutants or even prevent pollution. Additionally, in agriculture, genome mapping endeavors to increase crop yields and develop plants that can better adapt to climate change.

One possible advantage of a genetic test that identifies genes increasing the likelihood of Alzheimer's disease is that it empowers individuals with the knowledge of their genetic predisposition, enabling them to make informed lifestyle changes or seek early medical interventions. A potential disadvantage is the psychological burden and stress of knowing one's heightened risk for a condition, along with potential privacy concerns or misuse of genetic information by insurance companies or employers.
