The phylogenetic trees we reconstructed with UPGMA are substantially similar to those by Nei and Roychoudhury, but the genetic distance estimated is twice as that estimated by them between Negroid and other races. The differentiation and evolution within C...             限制性片段长度多态性(RFLP)指用限制性内切酶切割特定基因后产生的一类多态性,不仅可广泛地应用于产前诊断,且对于人类学研究和民族迁移的探讨也有重要意义。本文以β珠蛋白、PAH和DMD基因连锁序列的RFLP频率为依据,分析三大人种间和人种内的分化演变。研究结果表明,本文以RFLP频率为依据构建的系统树在拓扑上与Nei等以基因座位频率为依据构建的树是一致的,但尼格罗人种和其他人种间的遗传距离却比Nei等以基因座位频率数据为据报道的大一倍左右,看来这是一个有待进一步探讨的问题。研究结果还指出,高加索人种内的分化演变约发生在距今9000年前,从而在分子水平上可靠地印证了人群地理迁移及历史语言学论断。本文还初步分析了遗传距离与遗传病发病率的关系,经双对数变换处理后,两者似呈现负相关,或许提示DNA水平上的多态性维持机制可用中性突变学说来解释。 文摘来源          It was believed that there was no special therapy for Leber's heredita ry optic neuropathy.
