Simulate Your Grandparents

Simulate Your Grandparents is a simple yet powerful tool that takes your G25 coordinates and simulates possible combinations of 4 or 8 modern individuals whose averaged DNA matches your own.

Paste your G25 data (labeled or not) and let the engine calculate the most compatible ancestral mixes. Whether you're just curious or investigating hypotheses about your deep roots, this tool helps you see what combinations make you.
