I was lucky in that I was able to DNA test both paternal grandparents, as well as my maternal grandmother before she died last year. I have also tested my mother, but unfortunately my other grandfather died a few years ago. Nevertheless, in theory I should be able to nearly completely phase my DNA matches into each grandparent.
GEDmatch has its phasing tool but this only works for parent-child phasing, not grandparent-grandchild phasing.
I can phase my mother's matches using her mother's kit, but this doesn't help with phasing my matches. I have not tested my father since I was able to test both his parents.
Any suggestions on how this might be achieved? I am open to using tools on GEDmatch or other resources.
