   台湾籍旅美老师今天交给我们的句子是:


  We can inherit a lot from our parents. Hair and eye color, height. But we can't inherit everything, because some biological traits are acquired during our lifetime. The only way to transmit biological information between generations is in the letters of our DNA 1.
  我们能遗传父母身上的很多特征:发色和眼睛颜色、身高等等。但也不是所有特征都是来自遗传,因为某些特定的生物特征(并非天生)是经由后天产生的。唯一能够将人们身上的生物信息遗传给后代子孙的方法就藏在我们的DNA编码当中。
  遗传的奥秘
