Genetic ancestry refers to the study of an individual's genetic makeup to trace their lineage and heritage. By analyzing DNA, scientists can identify genetic markers that indicate where a person's ancestors originated. This information can reveal connections to specific populations or regions, helping people understand their ethnic background. Many companies offer genetic testing services that provide insights into ancestry. These tests compare an individual's DNA to reference samples from various populations around the world. Results can show percentages of ancestry from different regions, such as Europe, Africa, or Asia, offering a clearer picture of one's genetic heritage.
