Firstly, what exactly is transgenic technology?and in want way are Glofish connected?
Apparently I have been told that they are fish(zebrafish?) that have had their DNA genetically altered by combining them with DNA of seaweed or jellyfish or something. I am not sure if this is all true/correct information but I am very interested and if anyone can help me understand the facts please help. Thanks.
