Mitosis vs. Meiosis

At the beginning of this unit I was lost when someone would ask me this same question, how is mitosis different from meiosis? Well now I can answer it. To begin with, mitosis is asexual reproduction while meiosis is sexual reproduction. However, the both go through the same stages of the cycle but the end is what separates them into two. In mitosis, there are two daughter cells that have the same exact DNA strand, while in meiosis the 4 daughter have half of the chromosome or DNA strand. This happens because of the two parents giving half and mixing them together. In mitosis the organism can reproduce by itself while in meiosis two "parents" are needed. In meiosis you get one set of chromosomes from your mother and one from your father. Basically in mitosis, the organism reproduces by itself duplicating its DNA, while in meiosis you need the two gametes for the reproduction to occur. At the end of meiosis the daughter cells have mixed genes from both parents. Over all, I have learned and preserved a lot of the information. I am really glad I was able to learn this so quickly and effectively as well.
