What is the difference between transgenic breeding technology and traditional breeding technology?

The history of human farming is the history of the great practice of human plant and animal breeding, which has produced the excellent varieties of plants and animals that we rely on today. In fact, the so-called conventional breeding is the transfer and convergence of many excellent genes between organisms of the same species or closely related species, but due to the natural law of "interspecies reproductive isolation," the limitations can not be utilized in non-homologous organisms of the excellent genes. Modern transgenic breeding technology realizes the purposeful cross-species transfer of genes, which can not only predictably strengthen the existing excellent characteristics of organisms, but also enable species to obtain completely new traits, which is more efficient and more predictable.
