The correct answer is Meiosis.

Explanation:

Meiosis is a specialized type of cell division that occurs in the formation of sex cells, or gametes, such as sperm and eggs in animals. Unlike mitosis, which is a process of cellular reproduction where one cell divides to form two identical daughter cells, meiosis involves two rounds of division and results in four non-identical cells, each with half the number of chromosomes of the original cell. This reduction in chromosome number is crucial for maintaining genetic stability across generations when gametes fuse during fertilization.

In summary, meiosis is essential for sexual reproduction and contributes to genetic diversity through processes such as crossing over and independent assortment.
