Tolan Recent Ancestors Jews

**Tolan Recent Ancestors — Jews (Modern)** Fine-scale autosomal admixture calculator optimized for modern-era (≈2–10 generations) ancestry. Compares your DNA to 29 regional reference populations—including Levant and European-Jews—to reveal recent admixture proportions, likely geographic sources, and genealogical leads. Ideal for genealogists, community researchers, and genetic enthusiasts.

About This Calculator

**Tolan Recent Ancestors — Jews (Modern)** This calculator analyzes autosomal DNA to estimate *recent* ancestral contributions by comparing your genome to a curated panel of 29 reference populations, with special emphasis on Jewish and Levantine-related signals. It is optimized to detect admixture from roughly the last 2–10 generations (modern-era ancestors) using allele-frequency and segment-level comparisons to highlight which regional source populations best explain your recent ancestry. Who it's designed for: - Genealogists and family historians tracing recent lineages - People exploring Jewish heritage and diaspora connections - Population geneticists and curious users seeking fine-scale, modern-era resolution What insights you can gain: - Quantitative proportions of recent ancestry from groups such as European-Jews, Levant, North_Africa, Iberia, Caucasus, East_Europe, Central_Asia and others - Geographic patterns consistent with known diasporas (e.g., Ashkenazi, Sephardi, North African Jewish mixing) and local host-population admixture - Context about whether signals reflect recent local admixture versus deeper, shared ancient ancestry Historical and genetic context: Jewish communities experienced repeated migrations and local intermarriage across Europe, North Africa, and the Middle East. By focusing on modern-era reference groups (including Levantine, European, North African, Central and South Asian, and African populations), this tool helps separate recent regional contributions from long-standing shared ancestry. Why this calculator is valuable: - Fine-scale, modern-era focus complements broader ancient ancestry tools - Translates genetic signals into testable genealogical hypotheses and regional leads - Accessible output for non-specialists with professional context for researchers Limitations and best practices: - Estimates depend on the breadth and quality of reference panels and may blur between closely related groups - Not intended for clinical

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 30 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 30 reference populations
Modern populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Modern populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
