Web22 jul. 2024 · The two factors are: crossing-over and independent assortment. Crossing over: In Prophase I of Meiosis I homologous chromosomes line up their chromatids and “cross-over” or exchange corresponding segments of DNA with each other. This produces genetic variation by allowing more combinations of genes to be produced. WebMitosis and meiosis, which are both forms of division of the nucleus in eukaryotic cells, share some similarities, but also exhibit distinct differences that lead to their very different outcomes. Mitosis is a single nuclear division that results in two nuclei, usually partitioned into two new cells.
