In fact, gene exchange, transfer and change is a common phenomenon in nature, and it is an important force to promote biological evolution. It is precisely because of gene changes that species can continue to have new traits, further development will produce new species, forming the nature of colorful biodiversity, our world can be so rich and colorful. Transgene is that scientists use engineering technology to transfer one or more genes from one organism to another, so that the latter can acquire new traits. For example, transgenic cotton, rice or corn that are resistant to cotton bollworm, leaf roller and corn borer will be developed by transferring insect resistant genes into cotton, rice or corn.

This technology is called gene modification, gene modification and genetic engineering in the world. In China, it is translated into "transgene". The earliest misunderstanding of transgene is that "eating genetically modified food will be genetically modified", which still exists today. Such a misunderstanding is the same as thinking that "people will become pigs after eating pork" or "mules will become infertile after eating mule meat". There are thousands of genes in food, and the one or several genes transferred into the food are quickly digested in the stomach like the other thousands of genes. They have no chance to "move" our genes. (source: mental confusion: genetically modified issues of public concern)
