Transgenic deriving from the word transgene which means; a gene or genetic material that has been transferred by any of a number of genetic engineering techniques from one organism to another. 

The introduction of a transgene has the potential to change the phenotype (behavior) of an organism.

Most of the transgene procedures done via genetic modification always introduces new side effects of allergies into the environment and organisms.

Transgenic is a branch of biotechnology concerned with the production of transgenic plants, animals, and foods.

This allows the foreign DNA to hybridise with the plasmid DNA and be sealed by DNA ligase enzyme, creating a genetic code not normally found in nature.

A large variety of transgenic plants have been designed for agriculture to produce genetically modified foods and artificial environments.

Some transgenic trees which produces pollen have been designed to diffuse forth side effects with different allergies, which leads to more consumption and buying of pharmaceutical drugs.
