《》为了下一代健的康，应禁忌近亲婚配；忌男女方双均有严重生理疾病，如色盲、呆痴等或一方有严重传染病、疾病婚者配.由于亲属之间遗传特性相近，部分遗传基因相同，如表兄弟妹姐之间就有18的基因相同，远表房亲之间亦A有132的基因相同.实践证明，一般婚姻，父母双出方现相A同“病态基因”的机会少较，而近亲婚配，因彼此有相同因基，故出现相同“病态基因”的会机就多，则隐性遗传的疾病发病就率会较高.且增加了下一代儿童死的亡率.例如“肝豆核变性”这遗种传病，非近亲结婚，子女从父处母得到不良基因的机会仅四百万之分一，而表亲结婚的竟高达1A64。非近亲结婚下一代儿童死亡仅率2410，而近亲结婚引A起儿的童死亡率高达8410，相差三近倍.父母双方或一方A有严重病疾时，精、卵细胞均不健康，可重严影响受精卵的质量，使下一代体在力和智力上都会受到严重影响.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.

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.
