Whoa, hold on a minute! By that reasoning, *all* tropical fish & plants
should be banned anywhere the environment would allow them to survive.
Using zebrafish as an example. Glowing or non-glowing, if they are let loose
in areas where they can thrive but are not native, they may well outcompete
native fish or harm native plants - in other words, damage the ecological
balance. This has just nothing to do with whether they are GM or not - it is
strictly a matter of introducing non-native species, which is almost always
a bad idea IMO.
But let's say that glowing zebrafish are released into a healthy, native
zebrafish population, and lets also assume that they haven't been so
modified by years of captive breeding that they can survive. Will they
replace the native, non-glowing fish? I don't know what the heritability of
the glowing gene is - if a glower and a non glower mate, will they have all
glower childen, all non-glower, or some mixture of the two? Are glower genes
dominant and recessive, like eye color? Where is Gregor Mendel when you need
I just think it's really important not to confuse the issues related to
genetic modification with those related to invasive non-native species.
Has anybody ever seen these things in person?
