Final answer:
Genomics can be used to analyze genetic variations and predict disease risk and treatment options based on an individual's genetic profile for certain diseases. It is especially effective for single gene mutations and provides valuable insights even for complex diseases influenced by multiple genes and environmental factors.
Step-by-step explanation:
Genomics can be used to predict disease risk and treatment options by analyzing genetic variations that may predispose individuals to certain diseases and identifying potential drug responses based on genetic profiles. By studying an individual's genome, scientists can determine their susceptibility to certain diseases and develop personalized treatment plans. This approach is most applicable when the disease is caused by a single gene mutation. However, for common diseases like heart disease, which are influenced by multiple genes and environmental factors, genomics can still provide valuable insights into disease risk and potential treatment options.
