问题 People in a large area any possess the same DNA thread because______. [br] If two men suspected for some reason they have a common ancestor,______.
选项 A、we can decide according to their family tree
B、we can find the truth from their genetic markers
C、we can compare the differences in their Y chromosome
D、we can look for written records to prove their relationship
答案 B
解析 细节题。由题干two men可定位至第三段第二句…if two men sharing the same last name…looking for common markers(如果两个同姓的人相信他们有共同的祖先，那么可以通过采集两个人的DNA样本寻找共同的遗传标记来确定这种可能性)，B符合。
