Segments in common

 

23andme. Chromosome browser comparison.

I'm continuing to work with DNA data and the chromosome browser tools on FTDNA, MyHeritage and now 23andme. Looking at some DNA matches on the Portillo and Campuzano side of the tree who tested at 23andme, I can see segments in common. I'm exploring a theory that may help resolve a question of multiple relationships, and better place Mariana Portillo on our tree in connection with my 3rd-great-grandfather Manuel Portillo.

Some additional new test information has arrived that calls into question some of what we've thought on the Mexican side of the tree. I'm hoping using the chromosome mapping tools will untangle these complications.
