Cousin Marriages


Book Description

Juxtaposing contributions from geneticists and anthropologists, this volume provides a contemporary overview of cousin marriage and what is happening at the interface of public policy, the management of genetic risk and changing cultural practices in the Middle East and in multi-ethnic Europe. It offers a cross-cultural exploration of practices of cousin marriage in the light of new genetic understanding of consanguineous marriage and its possible health risks. Overall, the volume presents a reflective, interdisciplinary analysis of the social and ethical issues raised by both the discourse of risk in cousin marriage, as well as existing and potential interventions to promote “healthy consanguinity” via new genetic technologies.




Consanguinity in Context


Book Description

An essential guide to this major contemporary issue, Consanguinity in Context is a uniquely comprehensive account of intra-familial marriage. Detailed information on past and present religious, social and legal practices and prohibitions is presented as a backdrop to the preferences and beliefs of the 1100+ million people in consanguineous unions. Chapters on population genetics, and the role of consanguinity in reproductive behaviour and genetic variation, set the scene for critical analyses of the influence of consanguinity on health in the early years of life. The discussion on consanguinity and disorders of adulthood is the first review of its kind and is particularly relevant given the ageing of the global population. Incest is treated as a separate issue, with historical and present-day examples examined. The final three chapters deal in detail with practical issues, including genetic testing, education and counselling, national and international legislation and imperatives, and the future of consanguineous marriage worldwide.

Your DNA Guide - the Book


Book Description

You don't have to learn everything about genetic genealogy before asking specific questions of your DNA! That's the premise of Diahan Southard's brand new book, Your DNA Guide - the Book, now available for pre-order at a special sale price. Your DNA Guide - the Book is like no other genetic genealogy book on the market. Instead of learning more-than-you-need-to-know in textbook style, you'll choose a specific DNA question to start exploring right away. You'll follow concrete step-by-step plans, learning important DNA concepts--in plain English--as you go. Do you want to learn who your 2X great grandmother is? Turn to page 23. Do you want to know how you are related to one of your DNA matches? Page 37. As you proceed, you check your progress and get new guidance based on your specific results at each stage. (Including troubleshooting, like when your matches just aren't responding or your great-grandparents turn out to be first cousins.) This powerful, hands-on approach is based on Diahan's 20 years of experience in the genetic genealogy industry and especially in the past five years, as she helps clients one-on-one make DNA discoveries. It became clear to her that while each client's situation may be unique, there are patterns in how you can find solutions that you can apply yourself. Your DNA Guide - the Book is for anyone who has taken a DNA test or may want to. It helps genealogists reconstruct family trees. It helps adoptees identify biological relatives. It can help you identify a specific DNA match. In short, it helps anyone explore what their DNA--and their DNA matches--can tell them about their origins.




Incest and Influence


Book Description

Like many gentlemen of his time, Charles Darwin married his first cousin. In fact, marriages between close relatives were commonplace in nineteenth-century England, and Adam Kuper argues that they played a crucial role in the rise of the bourgeoisie. Incest and Influence shows us just how the political networks of the eighteenth-century aristocracy were succeeded by hundreds of in-married bourgeois clans—in finance and industry, in local and national politics, in the church, and in intellectual life. In a richly detailed narrative, Kuper deploys his expertise as an anthropologist to analyze kin marriages among the Darwins and Wedgwoods, in Quaker and Jewish banking families, and in the Clapham Sect and their descendants over four generations, ending with a revealing account of the Bloomsbury Group, the most eccentric product of English bourgeois endogamy. These marriage strategies were the staple of novels, and contemporaries were obsessed with them. But there were concerns. Ideas about incest were in flux as theological doctrines were challenged. For forty years Victorian parliaments debated whether a man could marry his deceased wife’s sister. Cousin marriage troubled scientists, including Charles Darwin and his cousin Francis Galton, provoking revolutionary ideas about breeding and heredity. This groundbreaking study brings out the connection between private lives, public fortunes, and the history of imperial Britain.







The Right Spouse


Book Description

The Right Spouse is an engaging investigation into Tamil (South Indian) preferential close kin marriages, so-called Dravidian Kinship. This book offers a description and an interpretation of preferential marriages with close kin in South India, as they used to be arranged and experienced in the recent past and as they are increasingly discontinued in the present. Clark-Decès presents readers with a focused anthropology of this waning marriage system: its past, present, and dwindling future. The book takes on the main pillars of Tamil social organization, considers the ways in which Tamil intermarriage establishes kinship and social rank, and argues that past scholars have improperly defined "Dravidian" kinship. Within her critique of past scholarship, Clark-Decès recasts a powerful and vivid image of preferential marriage in Tamil Nadu and how those preferences and marital rules play out in lived reality. What Clark-Decès discovers in her fieldwork are endogamous patterns and familial connections that sometimes result in flawed relationships, contradictory statuses, and confused roles. The book includes a fascinating narration of the complex terrain that Tamil youth currently navigate as they experience the complexities and changing nature of marriage practices and seek to reconcile their established kinship networks to more individually driven marriages and careers.




Genetic Disorders of the Indian Subcontinent


Book Description

The population of the Indian subcontinent consists of a fine amalgamation of people from diverse tribal, cultural, religious and social backgrounds. Mortality and morbidity from a vast number of medical and surgical conditions is significant and well above compared to the developed countries. Although a large component of the human health problem is related to infection, malnutrition and other preventable causes, a significant proportion is linked to hereditary factors reflecting in the form of chromosomal, single gene and complex medical diseases. Unusual and unique Mendelian disorders are not uncommon and a number of common medical conditions, such as ischemic heart disease and diabetes mellitus are relatively more prevalent among those living in the developing countries of the Indian subcontinent and as well as among the migrant population groups in the western world. However, true burden of the inherited disorders among the Asian Indians is not known, and probably underestimated. This text includes a detailed and concise account of the social and cultural diversity, medical demography, genetic epidemiology, consanguinity and common genetic disorders affecting people from the Indian subcontinent. In addition, specific issues of genetic services in various regions are addressed.




The Economics of Consanguineous Marriages


Book Description

The institution of consanguineous marriage-a marriage contracted between close biological relatives-has been a basic building block of many societies in different parts of the world. This paper argues that the practice of consanguinity is closely related to the practice of dowry, and that both arise in response to an agency problem between the families of a bride and a groom. When marriage contracts are incomplete, dowries transfer control rights to the party with the highest incentives to invest in a marriage. When these transactions are costly however, consanguinity can be a more appropriate response since it directly reduces the agency cost. The paper's model predicts that dowry transfers are less likely to be observed in consanguineous unions. It also emphasizes the effect of credit constraints on the relative prevalence of dowry payment and consanguinity. An empirical analysis using data from Bangladesh delivers robust results consistent with the predictions of the model.




‘Blood Is Thicker Than Water’ – Non-Royal Consanguineous Marriage in Ancient Egypt


Book Description

This volume presents, for the first time, evidence for non-royal consanguineous marriage in ancient Egypt. The evidence was collated from select sources from the Middle Kingdom to the Roman Period, and it has been used to investigate the potential economic and biological outcomes, particularly beyond the level of sibling and half-sibling unions.
