The aim of this project is to find the relationship path of a common ancestor with someone who you share X-DNA. When you share autosomal DNA and X-DNA with a match, based on the how much you share an autosomal DNA and using the unique inheritance pattern of X-DNA, the possible inheritance path can be arrived. It also has a debugging mode to explain how much DNA is passed on. The value in curly brackets is the shared cM passed on. The estimate by this tool is not very accurate, as accurate estimates are not possible in X-DNA, because of the nature how X-DNA is inherited.
