Haplogroup C (MTDNA) is a group of DNA that is inherited only from your mother. Your haplogroup can tell you where your ancestors might have come from. Haplogroup C is one of the most common ones and it's found in many parts of the world. It's especially common in places like India and Central Asia. People with Haplogroup C tend to have similar genetic traits which can help us understand more about their ancestor's culture and history.
