🧬 Your Secret Inheritance: The Maternal Code
Your nuclear DNA is a 50/50 mix of your parents, but your mitochondria tell a different story. They come 100% from your mother!
👩👦Because mtDNA doesn't get "shuffled" like nuclear DNA during reproduction, it remains nearly identical through generations of women. This allows scientists to trace your maternal lineage back thousands of years to a single common ancestor known as "Mitochondrial Eve" who lived in Africa roughly 200,000 years ago.
The Integrated Science: This makes mtDNA a "molecular clock" that helps us map the migration of early humans across the globe! 🌍👣
