What is the meaning of consanguineous marriage?
In clinical genetics, a consanguineous marriage is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0.0156 (Bittles 2001), where (F) represents a measure of the proportion of loci at which the offspring of a consanguineous …
What is a double cousin marriage?
A double cousin occurs when two siblings from one family marry two siblings from another family and both couples have children. Those children are first cousins to one another twice over, through both of their parents.

Can cousins marry in a highly consanguineous population?
In highly consanguineous populations, pedigrees with complex consanguinity loops arising from cousin marriages in successive generations are encountered leading to higher inbreeding coefficients. Reports on consanguinity rates may sometimes include marriages between third cousins or more distantly related individuals.
What is consanguinity marriage?
The marital or sexual relationship between two persons belonging to the same genre (family) is known as consanguinity marriage. This method is widely accepted in around one-fifth part of the world, i.e. Asia, North Africa, Switzerland, Middle East and some parts of China, Japan and India.

To report and compare consanguinity rates among different populations, the two parameters best used are the mean inbreeding coefficient and the rates of marriages between first cousins. Global consanguinity trends
Why are there limits to the number of consanguineous parents?
This arbitrary limit has been chosen because the genetic influence in marriages between couples related to a lesser degree would usually be expected to differ only slightly from that observed in the general population. Globally it is estimated that at least 8.5% of children have consanguineous parents.
