Both processes involve the duplication of chromosomes.

Here's why:

* Mitosis: The cell copies its chromosomes before dividing, ensuring that each daughter cell receives a complete set of genetic material.

* Meiosis: This process also involves chromosome duplication, but then the chromosomes are divided twice, resulting in four daughter cells with half the number of chromosomes as the original cell.

Let's look at why the other options are incorrect:

* They both produce genetically identical daughter cells: This is true for mitosis but not for meiosis. Meiosis produces genetically diverse daughter cells due to crossing over and independent assortment.

* They both occur only in germ cells: This is only true for meiosis. Mitosis occurs in all body cells for growth and repair.

* They both involve two nuclear divisions: This is only true for meiosis. Mitosis involves one nuclear division.
