Meiotic metaphase i
WebProphase I of meiosis is similar to prophase of mitosis because in both the nuclear envelope disappears, and spindle fibers start to form. They are different in that crossing over takes place in prophase I of meiosis. In what way is metaphase I of meiosis similar to metaphase in mitosis? How is it different?

The way in which the homologous pairs are oriented randomly with respect to the cell poles is referred to as the law of independent assortment and ensures a random and independent distribution of chromosomes to the daughter cells of meiosis I … WebDefinition: the first stage of meiosis I Organisms all use mitosis to create more cells in the body. Meiosis, a similar process, is used in some organisms to undergo the process of sexual reproduction. Within meiosis, there are many steps or phases, sometimes referred to as the meiosis stages.
WebMeiosis: Prophase I This stage starts meiosis and is the same as prophase of mitosis with one important change. As the chromosomes condense, they form groups of four chromatids called tetrads or bivalents. Close inspection reveals that each chromosome is replicated and consists of two sister chromatids.
