1. But parents of identical twins don't view one child as an organ farm for the other.
    但是，同卵双胞胎的父母并不会把一个孩子看作另一个孩子的器官作坊。

2. But so far the only evidence for a genetic component has been through statistics, the relationship being inferred mathematically from comparisons of twins and other such studies of close relatives.
    但迄今为止，遗传基因所占比重的仅有的证据只是一些统计数据，即，从对双胞胎的比较，以及对其他血缘接近者的研究中得出的数学统计关系。

3. Were the twins standing up ?
    那双胞胎站起来了吗?

4. The twins look as like as two peas.
    这双胞胎长得一模一样。

5. Twins separated at birth do sometimes share personality characteristics, but such characteristics in a cloned son or daughter would only be reminders of the child who was lost.
    一出生就被分离的双胞胎，有时可能有相同的个性特征，但是这种相同的个性特征表现在克隆的儿子或女儿身上，只能令人想起失去的孩子。

6. Jean and John are twins.
    琼和约翰是双胞胎.

7. Identical genes don't produce identical people, as anyone who knows a set of identical twins can tell you.
    相同的基因不会复制出相同的人。这一点，任何认识一些双胞胎的人都可以告诉你。

8. In fact, twins are more alike than clones would be, since they have at least shared the same environment within the mother, are usually raised in the same family, and so forth.
    事实上，双胞胎相像的程度胜于克隆人，因为他们至少在母体内分享过相同的环境，通常也在同一个家庭里被抚养长大，等等。

9. If cloned animals could be used as organ donors, we wouldn't have to worry about cloning twins for transplants.
    如果把被克隆的动物用作器官捐赠体，那我们就不必考虑为器官移植而克隆双胞胎了。

10. In other words, the two are identical twins; only Dolly is six years younger.
    换言之，二者是一对同卵双胞胎，只是多莉小六岁。
