1. What is DNA Ancestry Analysis?

DNA ancestry analysis examines specific regions of your DNA to estimate your genetic heritage and ancestral origins. It compares your DNA markers with reference populations from around the world.

2. How DNA Ancestry Works

The analysis process involves:

Where:

• \( DNA\_data \) — Your raw DNA sequence data
• \( process \) — Algorithm comparing your DNA to reference populations
• \( ancestry \) — Estimated percentage breakdown of ancestral origins

Explanation: The algorithm examines hundreds of thousands of genetic markers to determine which populations your DNA most closely matches.

3. Importance of DNA Analysis

Details: DNA ancestry testing can reveal your ethnic mix, help trace migration patterns of ancestors, and connect you with genetic relatives.

4. Using the Calculator

Tips: Paste your raw DNA data (usually in TEXT or CSV format from testing companies) into the input field. The analysis typically takes a few seconds.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is DNA ancestry testing?
A: Accuracy depends on the reference database size. Major companies are about 95-99% accurate for continental-level ancestry.

Q2: What's the difference between ancestry and ethnicity?
A: Ethnicity is cultural, while ancestry is genetic. Your DNA ancestry might not match your self-identified ethnicity.

Q3: Why do results vary between companies?
A: Different companies use different algorithms and reference populations, leading to variations in results.

Q4: Can DNA tests determine specific countries?
A: Most tests can identify regions within continents, but country-level identification is less precise.

Q5: Is my DNA data stored or shared?
A: Our calculator processes data temporarily but doesn't store it permanently. Commercial companies have different privacy policies.
