Abstract
Disclosed herein relates to a method that improves the accuracy of producing family trees. The DNA of a target individual is processed to find a matching individual. Using the known family tree of the matching individual, multiple candidate family trees are generated with multiple proposed placements for the target individual. For each candidate family tree, a genetic likelihood for a proposed relationship and the other DNA test takers in the family tree. A birth-year probability is determined by identifying a most recent common ancestor (MRCA). The birth-year probability is based on the number of years between the target individual and the matching individual and a normal distribution of ages for parent-child age differences in a population. The genetic likelihood is converted to a genetic probability so that it can be compared with or added to the birth-year probability. Based on the two probabilities, the candidate family trees are sorted.
