What Is Chromosome-Level Traits Origins?
Every trait in your DNA exists at specific locations on your chromosomes. These locations, called SNPs (Single Nucleotide Polymorphisms), carry not just information about your traits, but also clues about where those genetic variants originated.
This analysis cross-references your trait SNP positions with your ancestry composition data to reveal which ancestral populations contributed the genetic variants at each trait location. You'll see the geographic origins of your genetic characteristics at the chromosome level.
By uploading an ancestry composition file (from 23andMe, FTDNA, RFMIX, or similar sources) alongside your trait data, you can discover which ancestral populations are present at each trait location, providing a deeper understanding of how your traits connect to your heritage.
Your traits carry the stories of where your ancient matches lived and adapted.

Why Trait Origins Matter
Understanding where your traits come from adds a new dimension to genetic analysis. It connects the "what" of your traits to the "where" of your ancestry, revealing patterns of inheritance and migration.
When you see that a particular trait variant came from a specific ancestral population, you're glimpsing into the history of that genetic variant — how it spread, where it was selected for, and what environmental pressures shaped its distribution.
This analysis helps you understand not just what traits you have, but the ancestral pathways those traits traveled. It's a bridge between trait analysis and ancestry exploration, showing how your genetic characteristics connect to geographic origins.
"Every genetic variant carries a passport from its ancestral homeland."

How It Works
Simple steps to discover the ancestral origins of your traits
Getting Started
The analysis requires your trait data and an ancestry composition file. Here's how to use it.
Select Your Sample
Choose a DNA sample that has been analyzed for traits. Only samples with Traits or Starter Pack license are available.
Upload Ancestry File
Upload an ancestry composition file from 23andMe, FTDNA, RFMIX, or similar sources. Supported formats include CSV, TXT, MSP.TSV, and JSON.
Analysis Begins
Our system cross-references your trait SNP positions with the ancestry composition data to identify ancestral populations at each location.
Explore Results
View detailed results showing which ancestries are present at each trait location, with confidence ratings and visual chromosome mapping.
Your uploaded ancestry file is automatically deleted after processing. All data processing follows GDPR compliance standards.
See What Your Results Look Like
Here's an example of the detailed analysis you'll receive
Ancestry Color Legend
Eye Color
Your genetic variants suggest a higher likelihood of brown or hazel eye color, with ancestry contributions from multiple European populations.
Lactose Tolerance
Your genetic variant indicates lactose tolerance, a trait that originated in Northern European populations and spread through migration.
Bitter Taste Perception
Your genetic profile suggests moderate sensitivity to bitter compounds, with variants linked to Mediterranean and Central European ancestries.
What You'll Discover

Frequently Asked Questions
Chromosome-level traits origins analysis cross-references your trait SNP (Single Nucleotide Polymorphism) positions with your ancestry composition data. It shows which ancestral populations contributed the genetic variants at each trait location, revealing the geographic origins of your genetic characteristics at the chromosome level.
We support ancestry composition files from 23andMe Ancestry Composition, FamilyTreeDNA (FTDNA), RFMIX, and similar sources. Supported formats include CSV, TXT, MSP.TSV, and JSON. The file should contain chromosome segments with ancestry assignments.
Yes, you need either a Traits Report license or Starter Pack license to access this analysis. The feature requires trait data to be available for your sample, which is included in these packages.
Confidence ratings indicate how reliable the ancestry assignment is for each trait location. High confidence means the ancestry assignment is very reliable, Medium indicates moderate reliability, and Low suggests the assignment should be interpreted with caution. These ratings help you understand which results are most trustworthy.
Yes, your data security is our priority. Uploaded ancestry files are automatically deleted immediately after processing. All data processing follows GDPR compliance standards, and your genetic data is encrypted using industry-standard protocols. We never share your data with third parties.
Yes, the analysis includes an ethnicity filter that allows you to focus on traits associated with specific ancestral populations. You can select multiple ethnicities and see which traits have ancestry from those populations. There's also an option to hide "Broadly" ancestries for more specific results.
Single-SNP traits are determined by a single genetic variant at one location. Multi-SNP traits involve multiple genetic variants working together. For multi-SNP traits, you can view detailed tables showing the ancestry composition at each SNP location, revealing how different ancestral populations contributed to different parts of the trait.
Yes, for multi-SNP traits, you can export the detailed SNP-level data in CSV format. This includes chromosome positions, alleles, ancestry assignments, and confidence information for further analysis or record-keeping.
