Fraternal, or dizygotic, twins share 50 percent of their genes.

而异胞胎则只共享50%基因。

You have a dizygotic dichorionic diamniotic pregnancy.

您患有绒毛膜羊水妊娠。

Suppose you find that monozygotic twins are much more similar than dizygotic twins.

假你发现单子比子更相似。

Are monozygotic twins just as similar as dizygotic twins?

单子和子一样相似吗？

And was like, " Those are (laughing) diamniotic dizygotic twins." - That he saw all of them.

就像，“那些是（笑）羊膜异胞胎。” - 他看到了所有人。

For instance, monozygotic twins look more alike than dizygotic twins and maybe they have different and--they have more similar environments because of this similarity in appearance.

比如， 单子相貌更相似， 可能是因为他们有着不同、更相似环境。

So, if you do the standard behavioral genetic tests, and you by now know how to do them--you'd look for differences between monozygotic and dizygotic twins, you'd do the adoption comparison--you know adopted siblings and biological siblings.

所以， 如果你做标准行为基因测试，你现在已经知道如何做它们了——你会寻找同胞胎和异胞胎之间差异，你会做收养比较——你知道收养兄弟姐妹和亲兄弟姐妹。
