问题
People in a large area may possess the same DNA thread because ______ .
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。题干的表述相当于第三段第二句:“if two men sharing the same last name believe that they are related”,做题依据是本句的后半句:“we can verify this possibility by collecting a sample of DNA from both and looking for common markers"(我们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项符合此意。C意为“比较他们Y染色体的不同”,并非要强调不同,因此是错误的。
