Answer:
When we compare the feeding of larvae with royal jelly to raise queen bees with turning off the Dnmt3 gene
It can be said that the latter is more effective in terms of the number of queens that can be produced and the energy expenditure is much lower. Well, keep in mind that bee larvae only become queens when they receive large amounts of royal jelly. A royal jelly protein is what activates the mechanisms to be a queen bee, this jelly machinery the nurse worker bees.
Through genetic manipulation, the Dnmt3 gene can be turned off in any larva to produce a queen bee.
Reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.
