You first select a root person and then pick from the 4 options.
- Maternal Line - Simply lists the direct Female line
- MtDNA - goes to the top of the Maternal Line from the selected person and then lists all female descendants and first generation Males (who will have the same MtDNA)
- Paternal Line - Lists the direct Male Line including the root person
- Y Chromosome - goes to the top of the Paternal Line from the selected person and then lists all male descendants
The matching people are output as a result set so the tools under the Options (Gear) icon can be used to set a flag or save them to a named list for use to highlight diagrams or other uses.
