The degree of relative consanguinity can be illustrated with a consanguinity table in which each level of lineal consanguinity (generation or meiosis) appears as a row, and individuals with a collaterally consanguineous relationship share the same row. [5]
Upholding familial structure and assets, and ease of marital arrangements are valued among consanguineous marriages. [4] [5] Low age and a lack of awareness of the consequences of inbreeding are common in consanguineous marriages. [2] Consanguineous marriage is present in every religion, and cannot be accredited to any one religious mandate. [4]
Although the overall frequency of disease-causing alleles does not vary much between populations, the practice of consanguineous marriage (marriage between second cousins or closer relatives) has been common in some Jewish communities, which produces a small increase in the number of children with congenital defects.

The Fourth Lateran Council removed the second type of affinity rule and the new axiom became: "affinity does not beget affinity", which is the principle followed in the modern Catholic Church. [8] It also limited both affinity and consanguinity prohibitions to the fourth degree, but retained the same method of calculating, counting back to a ...
Cousin marriage is a form of consanguinity (marriages among couples who are related as second cousins or closer). While consanguinity is not unique to the Arab world, Arab countries have had "some of the highest rates of consanguineous marriages in the world". [1]
In law, a prohibited degree of kinship refers to a degree of consanguinity (blood relatedness), or sometimes affinity (relation by marriage or sexual relationship) between persons that makes sex or marriage between them illegal.
consanguineous (of two or more individuals) Closely genetically related; sharing a recent common ancestor (usually no more than three or four generations distant). The effect of consanguineous mating, also known as inbreeding, is to increase the probability that the progeny will be homozygous at any given pair of genetic loci. [14] conservation ...
The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921.
