Verified step by step guidance1
Understand that the question is asking about a type of cell division that results in four sex cells, each with half the number of chromosomes of the original parent cell.
Recall that meiosis is the process of cell division that reduces the chromosome number by half, producing four genetically distinct haploid cells (gametes).
Recognize that mitosis results in two identical daughter cells with the same chromosome number as the parent, so it does not fit the description.
Note that binary fission and budding are forms of asexual reproduction in unicellular organisms and do not involve halving chromosome numbers or producing four cells.
Conclude that meiosis is the correct process because it specifically produces four sex cells (gametes) with half the chromosome number, which is essential for sexual reproduction.
