我不知道你居然是双胞胎！你们是同卵双生还是异卵双生？

I didn't know you were a twin! Are you identical or fraternal?

如果同卵双生比异卵双生更相似，这就意味着基因影响了性状，例如遗传性。

If identical twins are more similar than fraternal twins, this means genes affect the trait, ie it is heritable.

爱丽丝和我长得很像，因为我们是同卵双生的双胞胎。

Alice and I look very similar, because we are identical twins.

非同卵双生胎是两个受精卵同时在子宫着床的结果。

Non-identical twins are the result of two fertilized eggs implanting in the uterus at the same time.
