Explicación
## Step 1Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.## Step 2The purpose of meiosis is to ensure that when the egg and sperm combine during fertilization, the resulting offspring will have the correct number of chromosomes.## Step 3Option A is incorrect because meiosis does not join the nuclei of the egg and sperm. This process is called fertilization.## Step 4Option B is also incorrect because meiosis does not divide the cytoplasm of the egg and sperm. This process is called cytokinesis.## Step 5Option D is incorrect because meiosis does not maintain the cell's original chromosome number. Instead, it reduces the number of chromosomes by half.## Step 6Therefore, the correct answer is option C, which states that meiosis reduces the cell's chromosome number by half. This is the primary purpose of meiosis in the formation of egg and sperm cells.
