Before DNA fingerprinting is used, suspects ______.
The attitude of the Federal Bureau of Investigation shows that ______.
选项
A、enough data are yet to be collected from various ethnic groups to confirm the unlikelihood of two DNA samples coming from two individual members
B、enough data of DNA samples should be collected to confirm that only DNA samples from the same person can match
C、enough data are yet to be collected from various ethnic groups to determine the likelihood of two different DNA samples coming from the same person
D、additional samples from various ethnic groups should be collected to determine that two DNA samples are unlikely to come from the same person
答案
D
解析
文章最后一段指出,联邦调查局宣布他们会采集更多的数据;以解决目前Lewontin和Hartl及其他研究人员存在的争论,证明只有来自同一个人的样品才能够完全吻合,避免因为来自同一民族不同成员的样品相同造成的误差,故选B。A“两份DNA样品不可能来自于两个人”本身逻辑错误。C本身为错误判、断,因为来自同一个人的DNA样品不可能不同。开展采集更多数据的研究的目的是证明相同样品来自同一人,并非要证明不可能来源于同一人,因此D错误。
