Question

The zebra danios are a new type of pet fish, marketed as Glo-Fish. The fish were produced by transferring genes from jellyfish (green and yellow fish) and corals (red fish) into regular zebra danio fish (striped blue and white normally) embryos. Which of the following statements is NOT true about these fish?

Answer 1

The GloFish is a patented and trademarkedbrand of genetically engineered fluorescent fish. A variety of different GloFish are currently on the market. Zebrafish were the first GloFish available in pet stores, and are now sold in bright red, green, orange-yellow, blue, and purple fluorescent colors. Recently "Electric Green", "Sunburst Orange", "Moonrise Pink", "Starfire Red", "Cosmic Blue", and "Galactic Purple" colored tetra (Gymnocorymbus ternetzi), an "Electric Green" tiger barb (Puntius tetrazona)[1] and a glo-Rainbow Shark (Epalzeorhynchos frenatum) have been added to the lineup. Although not originally developed for the ornamental fish trade, it is one of the first genetically modified animals to become publicly available. It is sold only in the United States, where it remains the only genetically modified animal to be publicly available. The rights to GloFish are owned by Spectrum Brands, Inc., which purchased GloFish from Yorktown Technologies, the original developer of GloFish, in May 2017.

Answer 2

Answer:

D)  

These fish could have been produced by introducing the DNA of a coral or jellyfish into an empty fish egg.

Explanation:

These fish could have been produced by introducing the DNA of a coral or jellyfish into an empty fish egg. This would not work. This would only work with the DNA of another fish, and would produce an exact zebra danio clone, NOT a glowing fish.
