Transgenic glowing fish invades Brazilian streams
I broadly agree that this is disastrous in the same sense that any invasive species is. But I take exception to this silly paragraph:<p>&gt; He worries, for example, that the fluorescence-endowing genes from the escapees could end up being introduced in native fish with detrimental effects, perhaps making them more visible to predators. “It’s like a shot in the dark,” he says.<p>This is no more likely than for other fish to get the same gene from the original jellyfish humans found it in. Unless there are close relatives of zebrafish in those streams which can cross-breed with the zebrafish, there is no chance of gene transfer.<p>On the other hand, if they can interbreed, then its likely their offspring will inherit glowing gene. But that would be merely a symptom of a problem: that of an invasive species genetics diluting those of a native species.
