婚姻禁忌

由於親屬之間遺傳特性相近，部分遺傳基因相同，如表兄弟姐妹之間就有18的基因相同，遠房表親之間亦A有132的基因相同。實踐證明，一般婚姻，父母雙方出現相A同“病態基因”的機會較少，而近親婚配，因彼此有相同基因，故出現相同“病態基因”的機會就多，則隱性遺傳的疾病發病率就會較高。且增加了下一代兒童的死亡率。例如“肝豆核變性”這種遺傳病，非近親結婚，子女從父母處得到不良基因的機會僅四百萬分之一，而表親結婚的竟高達1A64。非近親結婚下一代兒童死亡率僅2410，而近親結婚引A起的兒童死亡率高達8410，相差近三倍。父母雙方或一方A有嚴重疾病時，精、卵細胞均不健康，可嚴重影響受精卵的質量，使下一代在體力和智力上都會受到嚴重影響.Forthe nextgeneration's health, should be taboo next of kin marriage; bogey men and women both have a serious physical diseases, such as color blindness, dementia, etc., or one with serious infectious diseases, illness marriages. Because of genetic traits between relatives is similar to some of the same genes, such as the cousins among the 18 genes have the same distant cousins are also among the genes, A 132. Practice has proved that in general the marriage, both parents appeared relative to A with the "pathological genes" have fewer opportunities, while the next of kin marriage, because to each other have the same genes, it appears the same as "sick genes" opportunity, the more, then the incidence of recessive genetic diseases would be higher. and the increase in the next generation of child mortality rates. such as "hepatolenticular degeneration" This kind of genetic disease, non-consanguineous marriages, children from their parents at the opportunity to have a negative gene only 1/4000000, while the cousins to marry as high as 1A64. The next generation of child mortality of non-consanguineous marriage is only 2410, while the inbreeding cited A child mortality rate since 8410, a difference of nearly three times. Either one or both parents, A serious illness, the sperm and egg cell are not healthy, can seriously affect a fertilized egg The quality, so that the next generation of physically and mentally will be seriously affected.
