"There’s a new phasing tool on Gedmatch as well, called the Evil Twin Phasing. Gedmatch has long had a tool to phase the kits of two parents and a child to show what segments the child inherited from each. This tool created phased kits showing the DNA the child didn’t inherit: “the data that the parent(s) did NOT pass on to the child. It still represents DNA from the child’s ancestors, but the child did not inherit that DNA.”"
I also have a few evil cousins - the rest are not evil I presume. :)
