Answer:
haploid cells!
Explanation:
most body cells go through mitosis, which produces a cell exactly identical to the original cell.
what makes meiosis / sexual reproduction unique, is that they use zygotes. the male zygote (sperm) and female zygote (oocyte) go through mitosis TWICE so that they end up with half the number of things they need. When the oocyte and sperm combine during reproduction, the new cell will have a unique HALF from mom and a unique HALF from dad to make a whole unique cell!
