Understand that meiosis is a type of cell division that reduces the chromosome number by half to produce gametes (sex cells).
Recall that gametes are haploid (n), meaning they contain one set of chromosomes, while the parent organism is diploid (2n), containing two sets of chromosomes.
Recognize that meiosis starts with a single diploid (2n) parent cell, which undergoes two rounds of division to produce four haploid (n) gametes.
Note that the process does not start with multiple parent cells; it begins with one diploid cell that will divide.
Therefore, the number of parent cells meiosis starts with is one diploid (2n) parent cell.
