The type of cell division that occurs after a pig egg cell is fertilized is called mitosis.

Here's why:

* Mitosis is the process of cell division that produces two identical daughter cells from a single parent cell. This is essential for growth and development.

* Meiosis is the process of cell division that produces gametes (sperm and egg cells), which have half the number of chromosomes as the parent cell. This is how genetic diversity is maintained in offspring.

Since the fertilized egg cell needs to divide and create more cells to form a pig embryo, mitosis is the process involved.
