Summary Introduction
Introduction:
The transfer of genetic material between cells is divided into two major categories: horizontal and vertical mode of transfer. In the case of vertical gene transfer, the gene is passed from the parental organism to its own offspring. Gene is transferred between individuals of unrelated generations in horizontal gene transfer.
