Pełniejszy materiał źródłowy / excerpt

A cousin marriage is a marriage where the spouses are cousins (i.e. people with common grandparents or people who share other fairly recent ancestors). The practice was common in earlier times and continues to be common in some societies today. In some jurisdictions such marriages are prohibited due to concerns about inbreeding. Worldwide, more than 10% of marriages are between first or second cousins. Cousin marriage is an important topic in anthropology and alliance theory. 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. Other societies may take a neutral view of the practice, neither encouraging nor condemning it, though it is usually not considered the norm. Cousin marriage was historically practiced by Aboriginals in upper classes of Europe, Australia, North America, South America, Polynesia and Melanesia. In some jurisdictions, cousin marriage is legally prohibited: for example, first-cousin marriage in China, North Korea, South Korea, the Philippines, for Hindus in some jurisdictions of India, some countries in the Balkans, Belgium, Lithuania and 30 out of the 50 U.S. states. It is criminalized in 8 states in the US, the only jurisdictions in the world to do so. The laws of many jurisdictions set out the degree of consangui…

Uncovering the Molecular Signatures of Rare Genetic Diseases in the Punjabi Population.. Rare genetic diseases (RGDs) affect individuals, families, and healthcare systems worldwide. Population-scale genomic data remain largely restricted to Western cohorts with an estimated 10,000 RGDs. South Asian populations remain underrepresented in molecular, clinical, and genomic databases. This study presents the first preliminary molecular genetic characterization of RGDs in the Punjabi population of Pakistan. Data were collected from the provincial RGD registry at the Punjab Thalassemia and Other Genetic Disorders Prevention and Research Institute (PTGDPRI), Lahore. Families diagnosed using next-ge…

Ancient genomes reveal an extensive kinship network and endogamy in a Three-Kingdoms period society in Korea.. The burial complex of the Imdang-Joyeong site at Gyeongsan in southeastern Korea is notable for the large number of tombs constructed within ~100 years (fourth and sixth centuries CE) and widespread practice of human sacrifice. Analyzing genome-wide data from 78 individuals, we detected 11, 23, and 20 pairs of the first, second, and three-or-more-distant degree relatives, respectively, revealing a dense network of kinship in the Imdang-Joyeong society. We found five individuals from closely related parents, suggesting the practice of consanguineous marriage in both grave owners and…
