网上wiki:
A twin is one of two offspring produced in the same pregnancy.[1] Twins can either be monozygotic (in common parlance, "identical"), meaning that they develop from one zygote that splits and forms two embryos, or dizygotic ("fraternal") because they develop from two separate eggs that are fertilized by two separate sperm.
我看兔宝宝两个很像, 素以觉得是identical. 因为fraternal 的一般长得很不相。
