Ending with telophase-2 and beginning with prophase-1, this is, for 10 points, what process used by gendered organisms to form gametes, the splitting of one cell into four with half the number of chromosomes?
One of the first sub-stages of this process is the leptotene stage, and in females, this process produces three polar bodies. Also notable for the creation of tetrads that undergo recombination, or ‘crossing over', this is the only process that forms haploids in animals.
