    1. Asexual reproduction is done via mitosis. Mitosis produced two identical cells. This is false.

    2. There are other processes, such as crossing over, that increase the genetic variation during sexual reproduction.

    3. The environment can indeed cause genetic variation with temperature etc. This is correct.

    4. Mutations can obviously be the cause of the genetic variation. This is correct.

    The answer is F.
