Answer:
Meiosis
Step-by-step explanation:
Meiosis is the process that allows a species to produce new generations of individuals, because meiosis is the complementary process to fertilization, which allows the number of chromosomes of a species to remain constant over generations.
Meiosis refers to the process of cell division through which a cell has its chromosome number halved. By this process gametes (animals) and spores (plants) are formed. It consists of two consecutive divisions, called Meiosis I and Meiosis II. Both are subdivided into four phases, which have the same name as mitosis.
