The X chromosome lives a genetic and genealogical life all of its own because of its unique inheritance properties which vary depending on whether you are a male and inherit the X only from your mother, or a female an inherit an X chromosome from both parents.  Because of this, it’s a great, and often untapped, resource for genealogists.

I covered how this works in my blog titled X Marks the Spot.  Jim Owston, however, has gone another step further and documented how to phase that X chromosome, meaning how to assign pieces of it to specific ancestors.  This is a great educational piece and tool for us genealogists, so please, take a look:

Great work Jim!!!
