Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. They are identified as a class of genetically modified organism (GMO).
The main advantages of transgenic plants include larger yield, resistance to diseases and pests and capable of growing under stressful conditions, while their main disadvantages include allergic reactions, emergence of super-pests and loss of biodiversity.
Transgenic animals are animals (most commonly mice) that have had a foreign gene deliberately inserted into their genome. ... This results in the recipient animal giving birth to genetically modified offspring. The progeny are then bred with other transgenic offspring to establish a transgenic line.
