Although our previous published protocol was effective in giving students experience in gathering and analyzing raw genetic data, it offered only a brief introduction to the scientific method. We have now developed three follow-up projects that enable students to successfully carry out experiments of their own design. The first project, which builds directly on the chi-square analysis protocol, gave students the opportunity to test their hypotheses about the genotype and phenotype of GloFish using PCR, fluorescence microscopy, or test crosses. Although many of the students were carrying out these techniques for the first time, they all successfully produced data that could be used to evaluate their hypotheses. This makes the project a good choice for laboratories courses, where time to problem solve experiments that are not working is limited. The second project, done by Brianna Vick as an independent undergraduate research project, explored more complex genetic concepts to uncover why there are several shades of orange GloFish. The final project, done by Adrianna Pollak for a high school science fair, used GloFish and fluorescence microscopy as tools to learn about fluorescent proteins, light and color, and transgenes.

GloFish are NOT injected or painted! GloFish get their stunning colors from a fluorescence gene, just like many species of sea coral and marine fish. GloFish are born with their beautiful color and shine brilliantly under a blue or white light! 5 POUND GloFish AQUARIUM GRAVEL STONE FISH TANK DECOR FLUORESCENT COLORFUL PLANT #GloFish

Other than this, they are identical to regular zebra danios, with the exception that the geneticallymodified glofish have neon colors. Regular zebra danios are gold and blue striped or gold and silver striped fish. Both glofish and regular zebra danios are peaceful fish that do well in a community tank.The Glofish is a genetically modified zebra danio that comes in several different fluorescent neon colors such as red, green, orange, blue and purple. You can now get other species such as glofish tetras as well. The Glofish was genetically modified with the purpose to detect environmental pollution. Scientists were able to inject a fluorescent protein gene (from marine organisms) into the zebra danio embryos to create the glofish. There are no dyes or color injections into this fish. Successive offspring get the gene passed down to them from parents. They are still working on developing a fish to only fluoresce when in the presence of pollution and a portion of glofish sales goes to the advancement of this research.Originally created to detect environmental toxins, glofish have been for sale in pet stores since 2003 for the general public to buy and place in their aquariums. There is some concern about what mighthappen if these genetically altered fish find their way into natural rivers and streams. Thecreators of glofish state that they don't pose an ecological threat because glowfish, like regularzebra danios, won't survive in the wild because they are tropical fish and need a water temperatureof about 24-26 °C (75-79 °F). It's been five years now and so far there doesn't seem to bea problem. Although some people do question the ethics of selling genetically altered fish tothe public just because they are prettier than the original fish.GloFish® fluorescent fish are born brilliant! They are not injected or dyed. They inherit their harmless, lifelong color from their parents, and require the same care as any other community fish. GloFish are great for any home, office, or classroom and perfect for hobbyists and beginners alike. GloFish are available in six striking colorsBeing zebra danios, Glofish will need to be kept in a group of at least 6 or more for best results. There may be some in fighting among themselves but keeping them in groups should help limit their fin nipping tendencies. They also look very cool when kept in large schools. Keeping glofish under black lights and dark colored gravel is popular and they even have complete glofish aquarium kits available now.Tetra GloFish Fluorescent Yellow Plastic Aquarium Plant creates a new nature setting with artificial versions of exotic, hard to maintain plants. In addition to enhancing aquariums, these plants also provide shelter to reduce fish stress. Fun fluorescent colors stand out under GloFish blue lighting. GloFish Aquarium Plants will complete your GloFish experience and complement the fish!
