Graph theory[ edit ] While family trees are depicted as trees, family relations do not in general form a tree in the sense of graph theorysince distant relatives can mate, so a person can have a common ancestor on their mother's and father's side.
However, because a parent must be born before their child is born, a person cannot be their own ancestor, and thus there are no loops, so ancestry forms a directed acyclic graph. The graphs of matrilineal descent "mother" relationships between women and patrilineal descent "father" relationships between men are trees however.
Assuming no common ancestor, an ancestry chart is a perfect binary treeas each person has exactly one mother and one father, for two parents; these thus have a regular structure. A descendancy chart, on the other hand, does not in general have a regular structure, as a person can have any number of children, or none at all.
