I’m thrilled to unveil the Population Genetic Distance Explorer, a new interactive tool to dive into the genetic diversity of human populations. Discover fascinating insights into migration patterns, population history, and genetic variation. Want to jump in? Scroll to the Get Started Today section to access the app link. To unlock the full post and explore the tool’s premium features, upgrade to a paid subscription below the paywall.

The visually oriented can use the Matrix Explorer, an interactive tool to visualize Fst distances between all possible pairs.

The core interactive component of the app is the Population Pair Selector, located in the sidebar panel.

Key Components of the Population Pair Selector:

  1. Population 1 Dropdown: A searchable dropdown menu where you select the first population

  2. Population 2 Dropdown: A searchable dropdown menu where you select the second population

  3. Swap Button: An exchange icon that quickly swaps your two selected populations

  4. Distance Metrics Display: Shows the Fst value and interpretation for your selected pair

  5. Random Pair Buttons:

    • "Random High Fst Pair" for discovering populations with high genetic differentiation

    • "Random Low Fst Pair" for finding closely related populations

How it Works:

  1. Select any population from the "Population 1" dropdown

  2. Select any population from the "Population 2" dropdown

  3. The app instantly calculates and displays:

    • The Fst value (genetic distance) between the two populations

    • An interpretation of what that value means biologically

    • Where this pair falls in the overall distribution of genetic distances

About the Data

The previously launched app used a dataset that I had personally curated. This new app utilizes data from the Allen Ancient DNA Resource (AADR), a comprehensive curated compendium of ancient human genomes compiled by Mallick and Reich (2023). For this application, I have focused exclusively on modern populations to provide a clear view of contemporary human genetic diversity.

The AADR represents one of the most extensive collections of human genomic data available, making it an ideal foundation for exploring population genetic structure. By leveraging this resource, I've created an intuitive interface that makes complex genetic data accessible to researchers, students, and genetics enthusiasts alike.

Two Versions for Different Needs

I understand that different users have different needs, which is why I am offering two versions of the application:

Free Version (20 Populations)

The free version provides access to a carefully selected set of 20 populations that represent major global populations:

  • Amazonian

  • Gambian

  • Eskimo

  • British

  • Palestinian

  • French

  • Greek

  • Iberian

  • Italian_North

  • Punjabi

  • Peruvian

  • Siberian

  • Tibetan

  • Japanese

  • Han

  • Malawi

  • Luhya

  • Turkish

  • Ukrainian

  • Yoruba

This diverse selection allows users to explore genetic distances across different continents and population groups, providing a solid introduction to population genetics.

Premium Version (115 Populations)

For paid subscribers, I offer access to an expanded dataset containing 115 populations, including:

  • Adygei

This expanded dataset offers a more comprehensive view of human genetic diversity, including many populations not covered in my previous applications. While there is some overlap with the population set used in the other recent app, this collection is partly distinct and offers new opportunities for exploration.

Key Features of the App

This Population Genetic Distance Explorer includes several powerful features:

  1. Interactive Heatmap: Visualize genetic distances between populations in an intuitive color-coded matrix

  2. Population Comparison: Select any two populations to see their specific genetic distance (Fst value)

  3. Fst Distribution: Explore the distribution of genetic distances across all population pairs

  4. Population Statistics: View summary statistics for each population

  5. Filtering Options: Focus on specific ranges of genetic distances

  6. Random Selection: Discover interesting population pairs with the random selection tools

Get Started Today

The free version of my Population Genetic Distance Explorer is available now. Simply visit the app page to begin exploring genetic distances between 20 selected populations.

For researchers, students, and genetics enthusiasts who need access to the full dataset with 115 populations, consider subscribing to the premium service. Paid subscribers gain access to the complete dataset along with additional features and updates.
