What are the differences and similarities between transgenic and genetic improvement?

Transgenic technology refers to the introduction of artificially separated and modified genes into the genome of an organism, and the expression of the introduced genes leads to the heritable modification of biological traits. This technology is called transgenic technology. Genetic improvement refers to the selection of excellent genes and recombinants produced by natural mutation through traditional technology, and the accumulation of excellent genes through random and natural methods. In essence, there may be no difference. It's all about genetic improvement and recombination of organisms, but fifty steps and one hundred steps are related. However, the widespread application of transgenic technology is considered too radical, and people are worried that this technology will cause unknown and uncontrollable harm to human beings.
