Related marriage. Conversations about heredity.

 By Barashnev, doctor for medical science.

Long time ago are found at families, where staying in marriage are close relations, that children's was born inferior. But to explain it science  found today.A  history showed awesome experiments, showed examples for accumulations genetical diseases and slowly degeneration in these closed circles, where are received related marriages. And these are queen dynasties, where marriages appreciated of diplomatic considerations , and to the goal a keep clean queen s blood.

 If on a century our beginning American scientist Woods learned a pedigree for queen s homes Hannover's, Gogencollerns , Konde, Bourbons, Habsburgs, and found in these families are peoples ,suffered from  genetically diseases. And scientists worry are these past  days , but laws and traditions for many peoples are avoiding as preventing for related marriages, but still are popular in Asia, and sometimes  by  national or religion traditions, or  geographic conditions, as in small, hard access villages, deserts, mountains, islands , in regions with low hardness of livers. But by researches from India, North Sweden, on Islands of the Adriatic Sea  , North Africa, Cyprus's, Nigeria, Finland , and in a few Russian regions are children's dead by related marriage was born is high, they are often having inborn diseases, as a most hard in delay for mental development, blindness, muscle dystrophy, changes of bone system. And on the last speech are gone, that sicked children will be born in parents, which are healthy, but having a same changed gene. And  between members of this family are both carries these genes are higher, that in members not related, thus a raised risk for genetical diseases in children, as so transferring disease Tay-sax , where are having delaying in development and vision defects. And in analyses for children's was born by related marriage are finding in different generations common relatives, suffered from  obesity , mental backwardness, other psychical destroys, as by genetically not transferring these diseases, but organism peculiarities from, that predispositioned to disorders. And, by these checks are in a few regions done , which having in a few countries, and in one places children's by parents relatives suffers from blindness, mental backwardness, deafness, or  muscle dystrophy. And,  proved , that relatives'  connections are bad for favourable future generations, modern science is shown  ,for health damage for a community health affected are casteism, sectarianism, national isolation leading to creating between relatives. A growing for big countries, towns, industrial development a few regions are leading to no for related marriage, but mixed marriages as of different nationalities too growing. And its an importance in social factors for lowering numbers of genetical diseases. And what about a love and stayed in related marriage?And , a lot depending on  related level, that related is closed, thus a risk for children's was born sicked a higher. A for cousins by brother and sister is risk higher, than from second cousins, and importance is health condition by family members as on heritage generations, thus all these circumstances need to think and advice with specialists by medico-genetical consultations.But,  both are understood and decided about free children's staying, but its a staying for beginning years, later will display a wish to be a mum and dad, and situation staying dramatically.Thus,  think about it still and not wait, visit specialists!
