🔬Ethnicity results provide an estimate of your genetic heritage.
🌍Reference populations and mathematical algorithms are used to determine ancestry.
🗺️Different DNA testing companies may have different reference populations and naming conventions.
💡Recall and precision are important factors to consider when interpreting ethnicity results.
🧬Ethnicity results offer valuable insights into your ancestral makeup but are not always exact.
Are ethnicity results exact?
—No, ethnicity results provide an estimate of your heritage based on genetic analysis.
What are reference populations?
—Reference populations are the groups of people to whom your genetic makeup is compared to determine your ancestry.
Do different companies have different reference populations?
—Yes, different DNA testing companies use different reference populations.
What is recall and precision?
—Recall is the ability to identify everyone from a specific category, while precision is the accuracy of assigning individuals to the correct category.
How should I interpret my ethnicity results?
—It is important to understand that ethnicity results are estimates and to consider factors such as recall, precision, and the specific reference populations used by the testing company.
