Meaning of CONSANGUINITY:
Literally meaning of the same blood, the term is used in anthropology and in many legal systems to refer to a blood kinship tie. It is contrasted with ‘affinal, so that my bond with my son is consanguineous while my bond with my wife is affinal. In some societies, degrees of consanguinity are important for deciding the order of inheritance or for regulating choice of marriage partners. Because they share more of the same blood”, siblings are closer than cousins.
