Yes, I agree with statement b/c in meiosis I, specifically in prophase I the homologous chromosomes line and form tetrads in which they exhibit the act of ‘crossing over’ which allows for genetic diversity; This would not occur in mitosis as body cells are produced to repair or for growth so the division of cells must allow for the exact replication of DNA or it is not possible to repair the body or growth if there is genetic variation in each cell. Also, in Meiosis I, specifically when metaphase I occurs, it is impossible to predict how the homologous chromosomes will be split, therefore creating even more diversity of genes known as Independent assortment. None of these processes occur in meiosis II, as the exchange of DNA and act of genetic diversity has already occurred in Meiosis I, therefore Meiosis II simply has to go throwing regular cell division making it more similar to mitosis than Meiosis I; Independent assortment and crossing over are the processes that set Meiosis I to differ from the others.
