Thank you Ann, I understand the percentages and that (as long as it doesn't get to deep..LOL) .. Sorry guess I wasn't very Clear... It was the chart and how to use it for the X chromosomes (2) and if viewing the actual segments could tell you/me anything..
I appreciate the links, that was what I needed
