• replication of DNA within the cell

• the creation of a zygote

• the division of one cell into two identical cells

• the division of one cell into two unique cells

After meiosis, we end up with

• two gametes, each of which has the same number of chromosomes as the parent cell

• two gametes, each of which has half the number of chromosomes as the parent cell

• four gametes, each of which has the same number of chromosomes as the parent cell

• four gametes, each of which has half the number of chromosomes as the parent cell
