Inbreeding, inbreeding depression and extinction
Conservation Genetics, 2007Inbreeding is unavoidable in small, isolated populations and can cause substantial fitness reductions compared to outbred populations. This loss of fitness has been predicted to elevate extinction risk giving it substantial conservation significance.

Inbreeding and Inbreeding Depression
2020Inbreeding (also referred to as “consanguinity”) occurs when mates are related to each other due to incest, assortative mating, small population size, or population sub-structuring. Inbreeding results in an excess of homozygotes and hence a deficiency of heterozygotes.

An analysis of the rate of celibacy, under 2 criteria (at the ages of 30 and 40) among the offspring of consanguineous and non-consanguineous marriages did not show significant differences both among whites and non-whites (mulattoes and negroes), in a Central Brazilian region. There is, therefore, no evidence that rare recessive genes play an important

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.

Inbreeding and inbreeding avoidance in wild giant pandas
Molecular Ecology, 2017AbstractInbreeding can have negative consequences on population and individual fitness, which could be counteracted by inbreeding avoidance mechanisms. However, the inbreeding risk and inbreeding avoidance mechanisms in endangered species are less studied.

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
