DNA is an important new tool in genealogical research. You will find most of the
background information you need to understand DNA in the chapter The DNA
Detective. To supplement this information, you will find on this page premade Excel
spreadsheets for Most Recent Common Ancestor (MRCA) calculations that you
can experiment with to explore the effects of changing the various parameters on
MRCA results. You will also find sample files here for the NETW4108.exe
freeware computer program that you can use to model your own files for cladogram
generation. These files should work with updated versions of the program as they
become available on the Fluxus Engineering web site.
