    Incorrect Answer

    Only asexually 

    Incorrect Answer

    Mostly sexually 

    Incorrect Answer

    Mostly asexually 

    Correct Answer
    Explanation:

    Bacteria, being single-celled prokaryotic organisms, do not have a male or female version. Bacteria reproduce asexually. In asexual reproduction, the "parent" produces a genetically identical copy of itself. 

    Sexual reproduction does not occur in bacteria. But not all new bacteria are clones. This is because bacteria can acquire new DNA. This process occurs in three different ways:

    • Conjugation: In conjugation, DNA passes through an extension on the surface of one bacterium and travels to another bacterium (Figure below). Bacteria essential exchange DNA via conjugation.
    • Transformation: In transformation, bacteria pick up pieces of DNA from their environment.
    • Transduction: In transduction, viruses that infect bacteria carry DNA from one bacterium to another.
