AbstractWe have compiled data on the frequency of first‐cousin marriages in Finland using royal dispensation records for the time period 1810–1872 and national population statistics for the time period 1878–1920. For the earlier period, 0.315% of Finland's marriages were contracted between first cousins (2,331 of 739,387). During the second time period,

Clinical Genetics, 1986
The unique situation that the Norwegian 1891 census included information on consanguineous relation between spouses and that first admissions to psychiatric hospitals by diagnosis were available for the years 1921‐40, formed the basis for the present study.

Annals of Human Genetics, 1977
In Norway specified information of marriages between second cousins and closer relations has been recorded in the marriage certificates since January 1889. In addition, information was collected in the 1891 census and in the Medical Registration of Births (established in 1967). A ratio of second- to first-cousin marriages equal to or greater than 2 has

Invited review: Inbreeding in the genomics era: Inbreeding, inbreeding depression, and management of genomic variability [PDF]
Journal of Dairy Science, 2017 Traditionally, pedigree-based relationship coefficients have been used to manage the inbreeding and degree of inbreeding depression that exists within a population. The widespread incorporation of genomic information in dairy cattle genetic evaluations allows for the opportunity to develop and implement methods to manage populations at the genomic ...

Inbreeding and extinction: Effects of rate of inbreeding
Conservation Genetics, 2003Deleterious alleles may be removed (purged) bynatural selection in populations undergoinginbreeding. However, there is controversyregarding the effectiveness of selection inreducing the risk of extinction due toinbreeding, especially in relation to the rateof inbreeding.

A Generalization of the Inbreeding Coefficient
Biometrics, 1965SUMMARY It is shown that generalized quantities of inbreeding coefficient and of coefficient of parentage for linked loci tranisform through two kinds of matrices. As an example, expressions of a generalization of inbreedin-g coefficient is obtained for three linked loci, and recurrence relationships of the same quantity for an arbitrary number of ...

Average inbreeding or equilibrium inbreeding?
American journal of human genetics, 1986The equilibrium inbreeding is always higher than the average inbreeding. For human populations with high inbreeding levels, the inbreeding equilibrium is more than 25% higher than the average inbreeding. Assuming no initial inbreeding in the population, the equilibrium inbreeding value is closely approached in 10 generations or less. A secondary effect

, 2014 Increased relationships are a natural consequence of using only a few sires in an AI breeding program. Inbreeding can be avoided, but not without sacrifice of progress toward improved productivity.
