What does 2% DNA mean?

There is a general “rule of thumb” that we can apply when determining how far back we need to look in our family tree to find the ancestor who passed down our 2% DNA region. This general rule is based on the pattern of autosomal DNA inheritance where 50% of each parent's DNA is passed down to their offspring.
