1·Scientists have found a genetic mutation that appears to be the cause of Huntington's disease.

科学家们已经发现一个似乎是亨廷顿病病因的遗传突变。《柯林斯英汉双解大词典》

2·If a copy of a gene is a bit different from the original, that's called a genetic mutation.

如果一个复制的基因与原来的有些许不同，那就叫做基因突变。

3·Furthermore, the single copy of a founder mutation often confers a survival advantage on carriers.

此外，创始者突变的单一拷贝通常赋予携带者生存优势。

4·Cattle raising people in East Africa and northern Europe have gained a mutation that helps them digest milk as adults.

东非和北欧的养牛人发生了一种突变，帮助他们像成年人一样消化牛奶。

5·Norwegian scientists have analysed samples from more than 70 patients with clinical illness and no further instances of this mutation have been detected.

挪威科学家对从70多名临床疾病患者身上采集的标本作了分析，未发现更多的此类变异情况。

6·Their allele frequencies at numerous genetic loci gradually become more and more different as new alleles independently arise by mutation in each population.

随着新等位基因在每个群体中独立突变产生，它们在许多遗传位点上的等位基因频率逐渐变得越来越不同。

7·For example, the hereditary hemochromatosis mutation protects carriers from iron-deficiency because the mutated gene allows increased efficiency of iron absorption.

例如，因为突变的基因可以提高铁的吸收效率，所以遗传性血色素沉着病突变可以保护带菌者不缺铁。

8·While most disease-causing mutated are found in humans at a rate of one in a few thousand to one in a few million people, founder mutation can occur at much higher rates.

虽然大多数致病突变在人类中发现的概率为千分之一到百万分之一，但基础突变发生的几率可能高得多。

9·Founder mutations are a class of disease-causing genetic mutations, each derived from its own ancestral founder in whom the mutation originated.

创始者突变是一类引起疾病的基因突变，每一种都源自其自身祖先的“创始者”。

10·It was a silent mutation and was not associated with the traits of milk yield in buffalo.

这是一个无声突变，与水牛产奶量无关。
