HAPI-DNA is designed to provide resources to help you better understand your relationships to others using DNA. We are just beginning to roll out tools, so come back soon or join our mailing list below.

Welcome RootsTech visitors! The HAPI tool for reconstructing data from one parent is online!

Example tool output

Detect whether half-siblings or grandparent-grandchild pairs are related through their mother or father. This tool usually gives very high confidence results.

Use our simulator to generate segments for specific relationship types. Try simulating segments for use with the maternal and paternal relationship detector.
