6. Which of the following
meiotic processes increases genetic diversity? Because of cross over events that occur in prophase I of meiosis, genes on the same chromosome are not linked for eternity. Look at the example of crossing over in the text. Independent assortment, which refers to the left-right position of the duplicated homologues as they line up in pairs on the metaphase plate in metaphase I of meiosis is another way that gamete diversity is increased. Look at the diagram of metaphase I in your text. Understanding both mitosis and meiosis is greatly facilitated by studying diagrams. Be sure to carefully consider all diagrams.
