GloFish: These fluorescent fish were the first genetically modified (GM) animals sold as pets. They were initially developed for scientific research using genes from jellyfish and sea anemones to produce fluorescent colors.
Fast-Growing Salmon: AquaBounty Technologies has developed genetically modified Atlantic salmon (AquAdvantage salmon) that grow faster than conventional salmon.
Glowing Pigs: Researchers in China have genetically modified pigs to glow green under fluorescent light. This was done to explore techniques for inserting genes into animals for medical research purposes.
Spider-Goat: Genetically modified goats have been engineered to produce spider silk proteins in their milk. The silk proteins can be harvested and used for various industrial and medical applications.
Enviropig: The Enviropig was genetically modified to produce lower levels of phosphorus in its waste, aiming to reduce environmental pollution from pig farming.
Dolly the Sheep: Dolly was the first mammal cloned from an adult somatic cell using nuclear transfer. While not genetically modified in the traditional sense, the cloning process involved genetic manipulation.
Genetically Modified Mosquitoes: Scientists have developed genetically modified mosquitoes to combat diseases like malaria and Zika virus.
Belgian Blue Cattle: Belgian Blue cattle have been selectively bred and genetically modified to have a mutation in the myostatin gene, resulting in increased muscle mass, known as double muscling.
Genetically Modified Mice: Mice are common subjects for genetic modification in biomedical research. Scientists can alter their genes to study human diseases, test potential therapies, and understand gene function.
