What is the change in chromosome number in mitosis and meiosis?
Well, Mitosis never affects the chromosomal number! For example, all somatic cells (The cells that undergo mitosis) of humans will always have a chromosomal number of 46! think of it this way: Mitosis is a mechanism that ensures preservation of the species because DNA Normally decays, and the cells usually “Age”! Hence, there SHOULD be a process that allows “Renewal”! Are you with me? Btw, Mitosis results in TWO daughter cells! Good… On the other hand, meiosis is the process where a sex cell (of chromosomal number 2n. In humans, thats equivalent to 46 chrom) undergoes 2 divisions! The first being reductional, and the second equational in order to end up with FOUR daughter cells each having a chromosomal number of n (23 Chromosomes)! Im glad to help!
