Endogamy is the practice of seeking a marriage partner from within a group defined by social status, ethnic identity, family relationship or area of residence or some other distinct social characteristic. Endogamy is a cousin marriage in your family tree. True endogamy is the above situation repeated over and over and over again in your family history. In true endogamy, you share too much DNA with all of your cousins, given their actual genealogical relationships. Jewish and Acadian are good examples of historically endogamous communities. Some societies have rules of endogamy that specify marriage to a particular kinship-related partner. A low rate of endogamy suggests that a group is being assimilated into the surrounding society. Endogamy by social class is also known as social endogamy or social homogamy.
Historians have studied endogamy by region and age much more than endogamy by social class. Both endogamy and exogamy practices are defined by values and norms that may vary. Endogamic is of or pertaining to endogamy. Endogamous people practice endogamy. Indian populations are unique in their origin and have been practicing endogamy for thousands of years. Endogamy can be a major cause of infertility in Indian men, finds a new study published in Scientific Reports on April 18, 2019. Endogamy has influenced Hindu society and most of the 75,000 subcastes or subgroups of India's complex social stratification system.
Endogamy, consanguinity and community disease profiles. - Community Genetics. 2005: Bittles AH., Centre for Human Genetics, Edith Cowan University. Considerable attention is paid to the role of consanguineous marriage as a causative factor in the prevalence of genetic disorders. At the same time, the potential influence of community endogamy on overall levels of homozygosity and disease profiles remains largely under-investigated.
Endogamy and inbreeding since the 17th century in past malarial communities in the Province of Cosenza (Calabria, Southern Italy) - Danubio M. E.; Piro A.; Tagarelli A. - Annals of Human Biology, Volume 26, Number 5, 1 September 1999, pp. 473-488(16). Abstract: Endogamy rates were high in every village and decreased only in the present century as a consequence of the breakdown of isolation.
Effect of consanguinity and endogamy on mortality and fertility in a Spanish population, Genetica Iberica. 1985. Cereijo AI, Prieto L, Martinez-frias ML. The effects of inbreeding and endogamy on prenatal mortality and fertility in a Spanish population were analyzed using the data for control newborns registered in the Spanish Collaborative Study of Congenital Malformation. Educational level should be controlled in studies of the effects of endogamy and consanguinity, especially with regard to a variable like fertility that is so largely determined by the socioeconomic environment of the couple.
Surname Endogamy among the Brahmin of India - Suhasini Bhatnagar, Suraksha Agrawal - Current Sociology, Vol. 50, No. 6, 853-861. 2002 International Sociological Association. The study focuses on the effect of endogamy on genetic microdifferentiation. The groups are all subdivisions or classes of the Brahmin or priest caste, namely Bhargavas and Chaturvedis and Kanyakubja and Sanadhaya Brahmin, and all groups practise patrilineal surname endogamy. Two-generation pedigrees were drawn up and microdifferentiation was estimated using parameters like mean concordance, i.e. within-gotra marriages in Bhargavas and Chaturvedis, FIT (the inbreeding coefficient or inbreeding-like effect due to endogamy), FST and RST. The FST is almost the same in all the populations over two generations; however, it is slightly lower among Bhargavas and highest in Brahmin indicating that although these populations follow endogamy at surname level they are exogamous at gotra/kuldevi level. The same is indicated by FIS, which shows that in spite of strict endogamy there is no inbreeding-like effect in these populations.
