Mitosis/Meiosis?
it is important to the production of cells because meiosis is the process of producing these type of cell.s meiosis creates variation in the daughter cells because of the way the chromosomes separate during the process. remember that in meiosis I, the paired chromosomes (each chromosome containing 2 chromatids) separate from each other to form 2 daughter cells. let's give an example to make it easier to understand. let's use you. you're 46 chromosomes came from your mother and father. 23 of those chromosomes came from your mother and 23 from your father. in meiosis I, 23 chromosomes(again, i will emphasize that each has two chromatids) will go to one daughter cell and the other 23 set to the other daughter cell. now the 23 chromosomes randomly go to the daughter cells. so one daughter cell may have 21 chromosomes from your mother and 2 from your father, that means that the other daughter cell will have 2 chromosomes from your mother and the 21 from the father. again the combination of chromosomes will be different each time during meiosis. now in meiosis II, the chromatids of each chromosome will separate. and the result is 4 daughter cells with 23 chromosomes each and each chromosomes have each one chromatid.
