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

而异卵则只共享50%的基因。

You have a dizygotic dichorionic diamniotic pregnancy.

您患有卵绒毛膜羊水妊娠。

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， 单卵生子的相貌更相似， 可能是因为他们有着不同的、更相似的环境。

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

假设单卵生子比卵生子更相似。

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

就像，“那些是（笑）羊膜异卵。” - 他看到了所有人。

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， 果做标准的行为基因测试，在已经知道何做它们了——会寻找同卵和异卵之间的差异，会做收养比较——知道收养的兄弟姐妹和亲生兄弟姐妹。

Are monozygotic twins just as similar as dizygotic twins?

单卵生子和卵生子一样相似吗？
