　　·句子分析·
　　该句的主干是This DNA can reveal genetic information…，之后的about only one or two ancestors是宾语genetic information的后置定语，对其进行解释说明。
　　主句之后是由even though引导的让步状语从句，表示转折的意味，从句由两个分句组成，中间由or连接。
　　一个分句的结构是“主语(people) 谓语(have) 宾语(six other great-grandparents)”，第二个分句中省略了主语和谓语，因为主谓同一个分句，宾语是14 other great-great-grandparents。
