Which of the following is … Horizontal gene transfer is defined to be the movement of genetic material between bacteria other than by descent in which information travels through the generations as the cell divides. 3. Vertical gene transfer. The foreign DNA is either randomly inserted into the host genome or recombines if there is sequence homology between the two genomes. Medical MCQ Center Saturday, 19 January 2013. Because the resistance genes very often lie on transmissible gene sections, they can also be exchanged between bacteria of the same type or of different types (so-called horizontal gene transfer).
