Did You Know?
When discussing a mitochondrial DNA match, Abby says that there is a complete match, making the man who shares the match a full sibling. Not only do they need not be full siblings, they need not even be half siblings. Mitochondrial DNA is usually passed only from mother to child, with no male contribution; therefore any people with common female to female ancestry can have a complete mitochondrial match. Abby and the man in question could be third cousins, with mothers who were second cousins, grandmothers who were cousins, great-grandmothers who were sisters, and a great-great-grandmother who is the common mitochondrial ancestor. They could even technically be further removed than that. See more
