It is a video that explained meiosis the best although it might not have been the most funniest and entertaining. However, it teaches the basics of meiosis and gives a good visual of what happens during the process. It also explains why they divide the second time.
While watching this video as well as doing the activity in class I've learnt the differences between meiosis and mitosis. Mitosis is asexual reproduction while meiosis is sexual. Meiosis isn't greatly different that the other, however it starts with two pairs of chromosomes not one one. So after dividing once, each cell still has too many chromosomes. That results to a second phase, in which the steps are exactly like in mitosis. Also, during meiosis a process called crossover happens to mix the genes from the two different parents. If meiosis wouldn't have a second step, the baby would suffer drastic mutations.
