Studying populations through genetics

Population genetics looks at the inheritance of genes at the population level, which is at the heart of evolution.

Researchers in this field examine both the frequency and the interaction of genes and their variants (alleles) in a population. This information can be used, for example, to understand why one population is more or less susceptible to a disease than another.
