Gigatrees provides a free and easy way for users to upload their autogenerated anonymous DNA survey reports for aggregation into this DNA Survey. The charts shown above and below display the range of combined shared segment lengths for 3516 unique submissions. The accuracy of these charts will improve as more data is submitted (see Submitting Your DNA Report). Everyone is encouraged to participate. The ancestral generation of the nearest pedigree collapse will be displayed in parentheses and sample sizes for each unique relationship type are displayed in brackets. Tapping any colorized bar will display the min, mean, median and max values as well other statistical data. For an overview of how this data was calculated see, On Deriving the DNA Relationship Probability Table.
