Relationship predictions from Ped-sim!
The first ever relationship prediction tools from a peer-reviewed data source are here! One is a traditional relationship prediction tool and another is for known or suspected double cousin relationships. More recently, a percentage input box has been added, which makes the Orogen predictions the first ever to include X-DNA (for 23andMe data).
GEDmatch incorporates the relationship predictor from dna-sci.com!
You can read here about how GEDmatch is now using DNA-Sci relationship prediction probabilities on its One-to-Many tool.
A three-part series on using the kits of multiple tested relatives

The first ranges of X Chromosome DNA
If you’re interested in X Chromosome DNA, be sure to check in with this article from time-to-time as I update it with data for additional relationships. This is the only place to find shared X-DNA ranges. Data for great-aunts/uncles, half-great-aunts/uncles, and 2nd cousins once removed are now available.
The relationship predictors here are the only ones that use a peer-reviewed data source and the only to show differences between maternal and paternal relationships.
DOUBLE cousin PREDICTOR
This tool is similar to the above relationship predictor except that it includes 3/4 siblings, double 1st cousins, and many other double cousin relationships. You can’t find these in any other relationship predictors.
After using the GEDmatch “Are Your Parents Related?” tool, the best thing to do next is to enter the cM amount directly into this tool.
How much of an ancestor’s DNA do you have? How much would you be able to reproduce if you and various relatives all had your DNA tested?
