Consanguinity, or Degree of Kinship Degrees of consanguinity are used to compare the closeness of relationships in a legal context.
For instance, if a person dies without leaving a will, his estate will be divided according to a legally prescribed order.
Also, incest taboos prevent people marrying who are too closely related. Consanguinity can be lineal, where one person is an ancestor of the other, or collateral, where the two people have a common ancestor but neither one is an ancestor of the other. Computing lineal consanguinity is easy: Thus a father and son are related in the first degree, a grandfather and grandson in the second degree, and so on.
