Pharmacogenomics refers to the branch of research that investigates how an individual's genetic makeup influences their response to medications. This field combines pharmacology, which is the study of drugs and their effects, with genomics, the study of genes and their functions. By understanding genetic variations in drug metabolism and response, pharmacogenomics can help tailor medication therapies to individuals, improving efficacy and minimizing adverse effects.

The importance of pharmacogenomics lies in its potential to lead to personalized medicine—allowing healthcare providers to select the most effective drugs and dosages for patients based on their genetic profiles. This approach can be particularly beneficial for treating conditions like cancer, where the effectiveness of certain therapies can vary significantly among patients due to genetic differences.

In this context, the other options do not accurately reflect the definition of pharmacogenomics. The study of drug formulation, analysis of medication-related side effects, and evaluation of drug efficacy in different populations are important aspects of pharmacology, but they do not focus on the genetic factors that influence drug response, which is the essence of pharmacogenomics.
