3.25 understand that division of a cell by meiosis produces four cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes

Meiosis is when a cell splits in half, creating two copies, and then splits in half again to create four cells each with half the genetic information of a normal cell (haploid 23 chromosomes.)
This is how gametes are made.
