研究警告对濒危物种的遗传救援努力可能会带来有害的突变。 Study warns genetic rescue efforts for endangered species may introduce harmful mutations.

一项新的研究告诫说,促进濒危物种遗传多样性的遗传救援努力可能会带来有害的突变。 A new study cautions that genetic rescue efforts to boost endangered species' genetic diversity could introduce harmful mutations. 研究人员分析了响尾蛇,发现虽然这些努力增加了有益的突变,但也增加了破坏性的突变数量。 Researchers analyzed rattlesnakes and found that while these efforts increase beneficial mutations, they also raise the number of damaging ones. 研究显示,虽然总体效果可能仍然是积极的,但存在长期遗传损害的风险,要求对这类方案进行更多的研究和仔细监测。 The study suggests that while the overall effect might still be positive, there's a risk of long-term genetic harm, calling for more research and careful monitoring of such programs.
