Current research in genetic engineering will open a new path in breeding. People want to extract a certain DNA fragment from leguminous plant cells and use genetic engineering methods to insert it into non-legume plants to produce recombinant DNA that meets the requirements and form new varieties that can save nitrogen fertilizers. This research is currently ongoing.
On the one hand, the theories and methods of genetics are applied to the service of selection; on the other hand, certain selection practices will in turn enrich the theory of genetic selection. Through genetic selection, humans select for hereditary variations and create new biological types that can adapt to new environments and meet the needs of individuals.
Cell engineering: growing a cell into a complete individualbased on cellular totipotency, mainly observed in plant cells.
Genetic engineering: According to people's needs, useful gene fragments are transferred to carriers via DNA shearing enzymes and DNA ligases and connected to other gene fragments (the vectors are usually fungi, bacteria, etc.
< p>Genetic engineering: Based on Mendelian genetic effects, by analyzing the traits (DNA traits) of known individuals, we can derive the traits (DNA traits ) of unknown individuals and the rate of occurrence of the required traits
