After sending our DNA sample to National Geographic's Genographic Project, I found out that, based on our Y-chromosome lab analysis, my body carries a true African blood.
But why Y-chromosome? It is something which is passed directly from father to son, unchanged, from generation to generation.
If we trace my Y-chromosome back to the "good ol' days", here is simplistic version of the migration trail:
- 50,000 years ago: Originated in Northeast Africa in the region of the Rift Valley, perhaps in present-day Ethiopia, Kenya, Uganda or Tanzania.
- 45,000 years ago: Migrated to Middle East, perhaps in present-day Saudi Arabia.
- 40,000 years ago: Migrated to Persia, perhaps in present-day Iran and Kashmir and then to Northern India.
- 35,000 years ago: Migrated to Central and then to East China.
- 30,000 years ago: Migrated to Southeast Asia, perhaps in present-day Vietnam, and then to Borneo (not through Malay peninsula).
The point is:
- If you are still paternally related to my late grandfather, then your Y-chromosome is likely to have the same origin as mine. See our Rodovid family tree to see if yours meets mine.
- If people ask what race I am (like what they always do in Singapore!), they had better see this and figure out my genetic sequence for themselves.
The more people do this DNA analysis, the more we know where we come from. Go get your kit today!
