In this exercise we have to understand the concept of meiosis in order to define it as the amount of cells at the end is reduced.
Meiosis is a process of cell division in eukaryotic organisms, in which a diploid (2n) mother cell gives rise to four (three in the case of oogenesis) haploid (n) daughter cells.
In other words we can say that meiosis is a way to have a amout of cells is reduced in form a another life.
