D. it produces male and female sex cells
In meiosis, a cell
splits into four cells, also splitting the chromosome count in half from
the original cell. This is a critical stage for sexual reproduction in

have both male and female chromosomes and the resulting sex depends on
how the cells match up with those of the other parent.
