And we can look in particular at three types of siblings: identical twins, twins that actually share 100 percent of their genetic information and shared the same intrauterine environment, versus fraternal twins, twins that actually share 50 percent of their genetic information, versus regular siblings, also sharing 50 percent of their genetic information, yet not sharing the same intrauterine environment.
我们特别选取了三类兄弟姐妹 同卵双胞胎， 他们共享100%的 基因信息， 与其兄弟姐妹共享同一宫腔环境； 第二组是异卵双胞胎， 异卵双胞胎共享50%的 基因信息， 第三组是一般的兄弟姐妹， 兄妹，姐弟，或者姐妹， 也共享50%基因信息， 但经历不同的宫腔环境。
