In selective breeding, the desired genes from one organism are combined with genes of another organism, resulting in a new combination of genes.
<span>The selective breeding is quite voluntary and is not necessarily natural or congenital. It is the act of how people or individuals can choose traits in the gene pool of their choice to produce their desired or goal organism in the process. </span>

Answer:
The neutrophil is the first line of defense, it is called as PMN OR POLYMORPHONUCLEAR NEUTROPHIL, this cell is said to be the first line of defense for the first to reach the area of infection or in the area of trauma, this upon reaching that area (where it is attracted by defense chemomodulators) it recognizes the bacteria or the foreign body as an antigen, since these do not present the cellular histocompatibility complex of our organism, by recognizing it as an antigen, this cell can detect that it is not something typical of our body but something new that was inoculated, is how this phagocyte to the bacteria and induces its own programmed cell death.
In an injury or infection, the purulent collection is not only debris and pathogenic microorganisms, but they are dead cell bodies of PMNs that induce their own cell death with the battery inside to be able to inhibit its advance in our body, when this phenomenon passes the PMN it is called a peach.
Explanation:
In the event that no antibodies are present, it would not change much if it is the first time that the bacteria enters our body since the formation of antibodies by the lymphocyte cell line occurs as the last stage of immunity (neutrophils appear first, then the antigen presenting cells and finally the lymphocyte lineage in charge of making immunological memory with antibodies).
The PMN are guided more than anything by the humoral factor of the immune response, but the proinflammatory factor like cytokines or leukins, but not by the antibodies, that is why he wrote this process of bacterial assimilation in the response.
