Conjugation

Direct transfer of genetic material from one bacterium to another.

Two bacteria lie close together and a connection forms between them. 

After conjugation, crossing overtakes place between homologous sequences

In conjugation, DNA is transferred only from donor to recipient, with no reciprocal exchange of genetic material.
