Genetic Affinity

Genetic affinity refers to the degree of genetic similarity or relatedness between individuals or populations. It helps scientists understand how closely related different groups are based on their DNA. For example, people from the same geographical region or ethnic group often share higher genetic affinity because they have common ancestors. Studying genetic affinity can reveal historical migration patterns, evolutionary relationships, and how populations have interacted over time. Essentially, it’s a way to measure how much genetic material two groups share, indicating their degree of connection in the tree of human life.
