The number next to each box in the Table of<unk>  indicates the degree of relationship relative to the given person.<unk>  ("blood relation", from Latin<unk> s) is the characteristic of having a kinship with another person (being descended from a common ancestor). Many jurisdictions have laws prohibiting people who are related by blood from marrying or having sexual relations with each other. The degree of<unk>  that gives rise to this prohibition varies from place to place. Such rules are also used to determine heirs of an estate according to statutes that govern intestate succession, which also vary from jurisdiction to jurisdiction. In some places and time periods, cousin marriage is allowed or even encouraged; in others, it is taboo, and considered to be incest. The degree of relative<unk>  can be illustrated with a<unk>  table in which each level of lineal<unk>  (generation or meiosis) appears as a row, and individuals with a collaterally consanguineous relationship share the same row. The Knot System is a numerical notation that describes<unk>  using the Ahnentafel numbers of shared ancestors.
