This post was inspired by an excellent post from Lara Diamond today entitled “Long Segment–But No Close Connection“.
What is DNA Segment Frequency?
In addition to segment size, segment frequency may be another important consideration for genealogists.
There are two ways to think about segment frequency: The first measurement of segment frequency is the frequency of a DNA segment among all humans. This is a number that is currently unknown, and can’t yet reliably be estimated even with simulations; there just aren’t enough people in the world who have tested yet. This is especially true for a segment that might be found outside of people with European descent as testing of these populations has been minimal or practically non-existent.
