The Y-DNA STR 20 marker panel has been upgraded to include markers from the Y-44 panel that are most useful for the DNA clans indigenous research database.  This upgrade allows users with only 20 markers to maximize the number of populations that they can search using the indigenous DNA database.  All new Y-20 participants will be tested using the new panel.  Existing participants will be automatically upgraded to the new panel at no charge, but the upgrade will take place over an extended period of time due to the large number of participants in the system.  If you have any questions or would like to opt out of the upgrade, please contact us at support@genebase.com.  Please note that this upgrade only applies to Y-20 participants.  Please note that once the upgrade takes place, your “overlapping” markers will change for comparisons as you will be searching using a slightly different marker set.
