DNA Relationship Segment Ranges

Gigatrees5 users have the option to submit their DNA survey results anonymously and automatically without providing any personally identifiable information. By doing so, they are helping genetic genealogists develop more accurate prediction algorithms. The following table was created by aggregating the DNA relationship data from multiple submissions and is being displayed in real time.

This table shows the reported ranges of DNA segment lengths for various calculated relationships as they compare to total chromosome lengths. The Q1 and Q3 are respectively the 25% and 75% quartiles. The upper and lower cutoff values are also provided. Both will be used in the second table to calculate standard deviations.
