Cellular Division Mitosis- division of cosmetic cells, 99.9% cells of you body is going through mitosis, Meiosis- cell division in the formation of gametes, or sex cells. The end product has to have only half of the normal number of chromosomes. Half of the original is call the haploid. This is like this so that when half meets a partners half they can form a life that contains both gene of each partner. Mitosis- 46 92 unzips then floating nucleotides comes and connects with it then the cell divides where you have 2 new cells with 46 chromosomes. Meiosis- 46 92 DNA replication. During this phase you get “Crossing over”, before doubling there are single stranded chromosomes and after DNA replication there are double stranded chromosomes. In Mitosis they do this and then its over, but here part of the 2 double stranded can exchange information with each other. It’s the same information just swapping it out and crossing over allows for new combinations of genetic material that didn’t exist previously. o One through crossing over its through the first stage of crossing over. There are now 2 cells of 46, which are twice as many as we need so we then go through another division. o
