Question

which of the following is an example of a genetically modified organism?
fluorescent mice
organic strawberry
wild fish
regular tomato

Explanation:

A genetically modified organism (GMO) is one whose genetic material has been altered using genetic engineering techniques. Fluorescent mice are created by inserting genes (often from bioluminescent organisms like jellyfish) into the mouse genome to make them glow. Organic strawberries are grown without synthetic pesticides or fertilizers but their genes aren't altered. Wild fish have natural, unmodified genes. Regular tomatoes also have their natural genetic makeup unless specified as genetically modified (which this isn't).

Answer:

Fluorescent mice
