For example, it is now possible to analyze the DNA of an unborn child from the blood of its mother and determine its risk for diseases later in life. This opens the way to full-blown eugenics – the selection (by parents, authorities, or others) of children with characteristics considered “appropriate.”
尽管如此，最新技术进步所隐含的风险已变得日益明显。比如，现在已能通过母亲的血液分析未出生婴儿的DNA，确定日后患病的风险。这开启了充分优生（full-blown eugenics）的大门——（由父母、当局或其他人）选择有“合适”特征的孩子出生。
