Description

Definition

This variable reports why the NAPP variable US00A406 linked the person to a probable father. The NAPP establishes father-child links according to five basic rules, and this variable reports the number of the rule for the link in question. If a link could be made according to more than one rule, the lowest-numbered rule was applied.
