Advanced Admixture Modeling

Multi-Way Fits

Use statistical analysis to test complex ancestry models. Determine which combinations of ancient and modern source populations best explain your genetic composition using NNLS statistical fitting.

Discover Your Ancestral Origins

Use advanced statistical analysis to test which combinations of ancient and modern source populations best explain your genetic composition. Each model shows fit quality (p-value) and component percentages.

Advanced Admixture Analysis

1

Define Source Populations

Choose which populations to test as potential sources of your ancestry.

2

Statistical Modeling

Advanced algorithms test how well different mixture ratios explain your DNA.

3

Calculate Fit Scores

Each model receives a fit score indicating how well it matches your genetic data.

4

Identify Best Fit

Top-ranked models reveal the most likely ancestry composition and origins.

Understanding Your Results

Fit Score

  • •90%+ = Excellent fit
  • •80-90% = Very good fit
  • •70-80% = Good fit
  • •< 70% = Poor fit

Ancestry Percentages

  • •Show proportion from each source
  • •Add up to 100%
  • •Reflect optimal mixture ratio
  • •May indicate admixture events

Model Interpretation

  • •Top model most likely
  • •Similar high scores = uncertainty
  • •Single dominant model = clear ancestry
  • •Multiple good models = complex history

Frequently Asked Questions

You can test any combination of the 5,453 available references, selecting 2-4 populations to test as mixture sources.
Results are highly accurate when you have a clear ancestral signal. Complex or unusual ancestry may show lower fit scores or multiple competing models.
Yes, as we add more reference populations and improve methods, results may be refined. We notify users of significant updates.
