a specialized form of cell division occurs to form egg and sperm cells : Mitosis, Meiosis, Fertilization
What is Fertilization?
During fertilization, the main nucleus of an embryo is formed by the combination of a paternal sperm nucleus and a maternal egg nucleus. In reality, the process of fertilization in all organisms involves the union of the genetic material from two gametes, or separate sex cells, each of which has half the number of chromosomes that are typical for the species. In microorganisms and protozoans, the earliest type of fertilization involves the transfer of genetic material between two cells.
The fusing of the two gametes' membranes, which results in the creation of a channel that allows material to go from one cell to the other, is the first critical event in fertilization.

<h3>What is way of testing medicines?</h3>
In a laboratory, drugs are first subjected to non-human tests. These laboratory tests are performed to determine a level of safety.
The results of these tests are then submitted to the United States Food and Drug Administration (FDA), which determines whether the treatment is safe enough to be studied in human volunteers.
There are various phases involving discovery, clinical trial, review, and safety monitoring.
