Something We All Carry
Across cultures and continents, we all carry this quiet inheritance. Blood type is one of humanity's most universal genetic systems — a thread that connects us through deep time.
What Is Blood Type?
A simple genetic system we all share — explained with clarity, not complexity.
A Shared System
Blood type is a genetic system shared by all humans. It's one of the most universal markers we carry — present in every person, across every culture, throughout all of human history.
Subtle Variations
Blood types reflect small variations in markers on our blood cells. These differences emerged naturally over time and spread through populations as humans migrated and mixed.
Population Patterns
Different blood types are distributed differently across the world — not randomly, but shaped by thousands of years of migration, environment, and human connection.
Blood Type as Population History
What feels ordinary today carries a long human history.
Blood types aren't just medical categories — they're ancient genetic variations that tell the story of how humanity spread across the globe. Type O, the oldest blood type, traces back to our earliest ancestors. Types A and B emerged later, shaped by changing environments and the populations that adapted to them.
When you learn your blood type, you're not just receiving a letter and a symbol. You're glimpsing a piece of the larger human story — migration patterns, environmental pressures, and the gradual mixing of populations over thousands of generations.
"Blood type is a whisper from our ancestors — a genetic echo of journeys taken long before memory."

How to Read Your Results
Understanding what blood type ancestry means — and what it doesn't.
One Piece of a Larger Picture
Blood type is one small part of your genetics. It offers a window into ancestry, but it's just one of many genetic markers that together tell your complete story.
Context, Not Identity
Your blood type doesn't define who you are. It's a piece of biological context — inherited from your ancestors, but not a statement about your abilities, personality, or destiny.
Complements Broader Insights
Blood type ancestry works alongside other ancestry reports to give you a more complete understanding of your genetic heritage.
This report focuses on ancestry context, not medical advice. For health-related questions about blood type, please consult a healthcare professional.

The Scientific Foundation
Well-understood science, presented with care.
The ABO System
The ABO blood group system is one of the most important and well-studied genetic systems in humans. Discovered in 1901, it classifies blood into four main types: A, B, AB, and O. These types are determined by the presence or absence of specific antigens on red blood cells.
Our analysis examines specific genetic markers (SNPs) including rs7853989, rs8176722, and rs8176746 to predict your ABO blood type from DNA data.
The Rh Factor
The Rh factor (positive or negative) is another inherited characteristic of blood. It refers to the presence or absence of the RhD protein on red blood cells. Most people are Rh-positive, while Rh-negative is less common globally but varies by population.
We analyze marker rs590787 along with other variants to predict your Rh status from your DNA data.
Genetic Inheritance
Blood type follows predictable inheritance patterns. You inherit one allele from each parent, which combine to determine your blood type. The A and B alleles are co-dominant (both can be expressed), while the O allele is recessive (only expressed when two copies are present).
This inheritance pattern is why blood type has been studied extensively in population genetics — it provides a clear window into how genetic traits flow through generations and across populations.
"This is well-understood science, presented with care — grounded in decades of research, explained in human terms."
A Shared Inheritance
Some things remind us how different we are.
Others remind us how much we share.
Blood type is one of those quiet things that connects us — a simple inheritance carried by every human being.

Frequently Asked Questions
What is blood type ancestry?
Blood type ancestry looks at your blood type from a historical and population perspective rather than a medical one. It explores how blood types emerged, spread, and distributed across human populations over thousands of years.
How accurate is DNA-based blood type prediction?
Our prediction is based on well-studied genetic markers with high accuracy for most individuals. However, for any medical purposes, we recommend confirming your blood type with a clinical blood test.
Is this report really free?
Yes, the Blood Type Ancestry Report is completely free with no hidden charges. Simply upload your DNA data from any major testing company and access your report instantly.
What DNA file formats do you accept?
We accept raw DNA data from all major testing companies including 23andMe, AncestryDNA, MyHeritage, FTDNA, and other standard formats.
Does blood type determine personality or health?
This report does not make claims about personality or health. Blood type is a genetic marker with historical significance, but it does not define who you are or predict your future. We focus solely on the ancestry context.
How long does it take to get my report?
Once you upload your DNA data, the report is generated instantly. You can view and explore your blood type ancestry immediately after processing.
