Female fathead minnows (Pimephales promelas) exposed to copper (Cu) maternally transfer Cu tolerance to their larval offspring. Larvae produced after female parents received a sublethal 5-d, 100 microg/L Cu exposure had significantly greater survivorship in potentially lethal Cu solutions than larvae produced before those females were exposed to Cu.
暴露于铜（Cu）的雌性黑头软口鲦鱼（Pimephales promelas）会将对铜的耐受性母性传递给它们的幼体后代。在雌性亲鱼接受5天、100微克/升的亚致死性铜暴露后产出的幼体，在潜在致死性铜溶液中的存活率显著高于那些雌性亲鱼暴露于铜之前产出的幼体。
