1. What is MyHeritage Ethnicity Estimation?

MyHeritage analyzes your DNA to estimate your ethnic background by comparing your genetic markers with reference populations from around the world. This calculator helps interpret and normalize your ethnicity percentages.

2. How Does the Calculator Work?

The calculator normalizes your ethnicity percentages using the formula:

Where:

• \( genetic\_data \) — Array of ethnicity percentages from your DNA test
• \( \sum \) — Sum of all percentages (normalized to 100%)

Explanation: The calculator adjusts your raw percentages to ensure they total exactly 100%, making them easier to interpret and compare.

3. Understanding Genetic Ancestry

Details: Ethnicity estimates are statistical probabilities based on comparing your DNA to reference populations. They become more accurate as reference databases grow.

4. Using the Calculator

Tips: Enter the percentages exactly as shown in your MyHeritage results. Separate multiple values with commas. The calculator will normalize them to total 100%.

5. Frequently Asked Questions (FAQ)

Q1: Why don't my percentages add up to exactly 100%?
A: Due to rounding in the original report, they might not total exactly 100. This calculator adjusts them proportionally.

Q2: How accurate are these estimates?
A: Accuracy depends on the reference populations used. Broad regions are more accurate than very specific locations.

Q3: Why do my results differ from family members?
A: You inherit a random mix of DNA from ancestors, so siblings may get different percentages.

Q4: Can ethnicity percentages change over time?
A: Yes, as reference databases expand and algorithms improve, companies may update your estimates.

Q5: What does 0% of an ethnicity mean?
A: It means no detectable genetic markers from that population were found in your DNA sample.
