GTB-DYR, VERSION 2.4, LAST UPDATED MAY 15, 2012 Downloading Y-DNA Results E. DNA Reunion (Y-DNA) The DNA Reunion section allows you to search the database using your Y-DNA profile to find long lost family members in your Paternal lineage and discover potential links to your family tree. Requirements -‐ To use DNA Reunion, you must have at least 20 or more Y-DNA STR markers. -‐ This search feature only uses Y-DNA STR markers. Y-DNA SNP markers are not used for this search. Y-DNA matches When you search the DNA Reunion database, you are looking for other individuals who may share a common Paternal ancestor as yourself based on similarities in your Y-DNA STR profile. If your Y-DNA STR profile is very different from another person, it proves that you do not share the same Paternal lineage. Son #1: John Smith DOB: 1830 same Y-DNA STR profile as David Smith Brothers Y-DNA is passed down from father to son. Only males have Y-DNA so only sons can pass the Y-DNA down to the next generation. Common Paternal Ancestor Son #2: David Smith DOB: 1835 same Y-DNA STR profile as John Smith Reconnecting family using Y-DNA: These individuals can be re-connected through Y-DNA STR testing because they share a common Paternal ancestor and will have exactly the same or very similar Y-DNA profile. © 2012 DNA Ancestry Project | support@genebase.com 14
