Tutankhamun’s DNA: What Does It Tell Us About His Ancestry?
(Memes with no text will get you instantly banned.)
Understanding DNA can be tricky, but let’s break it down so a 12th grader can follow along. We’re looking at Y-STR markers, which are short sequences of DNA that only men inherit from their fathers. This means they can tell us about paternal lineage—basically, Tutankhamun’s direct male ancestors.
Step 1: What Are STRs and Why Do They Matter?
Think of STRs (Short Tandem Repeats) like genetic fingerprints. Different groups of people around the world tend to share certain patterns of STRs because their ancestors lived in the same places for thousands of years. Scientists have studied these patterns and grouped them into haplogroups, which help us trace back where someone's ancestors came from.
Step 2: Tutankhamun’s STR Values
In the 2010 study on Tutankhamun, scientists recorded two key STR values from his Y-DNA:
DYS393 = 13
Y-GATA-H4 = 11
Now, we compare these to known haplogroups to see where he fits best.
Step 3: Matching STRs to Known Haplogroups
Tutankhamun’s STR values perfectly match the haplogroup E1b1b (E-M78), which is most common in Egypt, Sudan, and Northeast Africa. This means his paternal lineage was native to the Nile Valley—not from the Near East (J1) or Europe (R1b).
Step 4: Why Does This Matter?
This challenges past assumptions that ancient Egyptian rulers had Near Eastern or European ancestry.
It shows that the 18th Dynasty pharaohs were deeply connected to indigenous North and East African populations.
It supports historical records that Egypt had strong links with Nubia and other African civilizations.

Final Conclusion:
Based on genetic science, Tutankhamun’s father and male ancestors were most likely from Northeast Africa, with strong connections to ancient Egyptian and Sudanese populations. His DNA does not match European or Middle Eastern haplogroups, confirming that the pharaohs of his time were biologically tied to the African continent.

Tutankhamun's STR Values:
DYS393 = 13
Y-GATA-H4 = 11
Comparison with Major Haplogroups:
1. E1b1a (E-M2) – West/Central Africa
DYS393: 12
Y-GATA-H4: 11
Partial match (1/2)2. E1b1b (E-M78) – Northeast Africa (Egypt/Sudan)
DYS393: 13
Y-GATA-H4: 11
Perfect match (2/2)3. J1 (J-M267) – Arabian Peninsula
DYS393: 12
Y-GATA-H4: 10
No match (0/2)4. R1b (R-M269) – Europe
DYS393: 13
Y-GATA-H4: 12
Partial match (1/2)Final Conclusion:
The best STR match for Tutankhamun’s paternal lineage is E1b1b (E-M78), which is most commonly found in Egypt, Sudan, and Northeast Africa. This supports the idea that the ancient Egyptian pharaohs of the 18th Dynasty were indigenous to the Nile Valley, rather than having Middle Eastern or European origins.
