Consanguinity
Consanguinity (kɒnˌsæŋˈɡwɪnɪti) is a term used in genetics and anthropology to refer to the property of being from the same kinship as another person. In that aspect, consanguinity is the quality of being descended from the same ancestor as another person.
Etymology
The word consanguinity is derived from the Latin word consanguinitas. The term is made up of con, meaning 'with' or 'together', and sanguis, meaning 'blood'.
Definition
Consanguinity refers to the genetic closeness of two individuals. It is the measure of how closely individuals are related to each other. The closer the biological relationship between two people, the higher the degree of consanguinity.
Degrees of Consanguinity
The degree of consanguinity between individuals is used to determine the prohibition of marriage in many cultures and legal systems, as well as to determine inheritance rights. The degree of consanguinity is calculated using a coefficient of relationship, which measures the proportion of genes that two relatives share.
