Degrees of “Cousin-ness”
A cousin marriage is a marriage where the partners are cousins i. The practice was common in earlier times, and continues to be common in some societies today, though in some jurisdictions such marriages are prohibited. In some cultures and communities, cousin marriages are considered ideal and are actively encouraged and expected; in others, they are seen as incestuous and are subject to social stigma and taboo.

Performed the experiments: LH. Analyzed the data: LH. Although a few hundred single nucleotide polymorphisms SNPs suffice to infer close familial relationships, high density genome-wide SNP data make possible the inference of more distant relationships such as 2 nd to 9 th cousinships. With data from populations, we show that the average amount of DNA shared IBD in most ethnolinguistically-defined populations, for example Native American groups, Finns and Ashkenazi Jews, differs from continentally-defined populations by several orders of magnitude.
Using these bounds as a guide, we detected tens of thousands of 2 nd to 9 th degree cousin pairs within a heterogenous set of 5, Europeans. The emergence of genotyping platforms that assay hundreds of thousands of sites across the genome has facilitated the rapid growth of databases with genome-wide data for human populations  — . These large databases may include data for pairs of individuals who are cryptically related over the last 10 generations, e.
Such cousins often share extended segments of DNA that are identical except for recent mutations. Genetic similarity metrics, such as the length of DNA segments that are consistent with identity by descent IBD from a common ancestor, can be used to detect relatively distantly related individuals  , . Because recombination breaks down these shared segments rapidly, pairs of relatives vary in the number and length of shared segments that they inherit from a common ancestor.
Fourth cousins, for example, may or may not share any long segments that are identical by descent . For a given pair of individuals, the inferred IBD pattern depends on a broad set of factors, including not only the rate and pattern of recombination, but also the accuracy of the IBD detection algorithm and the type of genetic data e.
