Have you ever wondered how many of your potential Family Finder matches actually show up on your match list? As you know, your mother gives you half of her DNA and your father gives you half of his, so half of your parents' DNA isn't a factor in DNA matching here at FTDNA. The result is that your match list doesn't actually show everyone in the database to whom you are potentially related.

Here are some numbers based on an actual family of three siblings:

Here are some numbers based on an actual family of three siblings:

- Each sibling's match list shows just over half of the total matches for the three of them together. This makes sense given that each person carries just half of the parental DNA.
- Therefore, looking at just one match list means not seeing nearly half of the total matches.
- Just over 11% of the total matches show up on all three match lists. In any given list, 20-23% of the matches are shared with both of the other two siblings.
