About
mitoYDNA is a free, nonprofit (501(c)3) crowdsourced database focused on Y-DNA and mitochondrial DNA data, designed to make genetic genealogy research accessible to everyone. Users can upload, compare, and explore their mtDNA and YDNA results in a collaborative, community-driven environment. One of its flagship tools, YSTR+, allows users to explore and compare up to 838 YDNA markers in a single interface, making it one of the most comprehensive YDNA comparison tools available for genealogists. A dedicated Chrome Extension is available to help users download their mtDNA files for easy uploading to the platform. mitoYDNA is entirely free to use and sustained through community support and merchandise sales via the mitoYDNA Gear store. The platform is supported by an active community on Facebook, Twitter, and a dedicated YouTube channel filled with how-to videos and tutorials. Ideal for genetic genealogists, hobbyist DNA researchers, and citizen scientists, mitoYDNA bridges the gap between raw DNA data and actionable family history insights. Whether you're tracing maternal lineage through mtDNA or paternal lineage through YDNA, mitoYDNA provides the tools and community to support your journey.
