WebbThe process of mitosis consists of four stages: prophase, metaphase, anaphase, and telophase. In prophase, the chromosomes condense and the nuclear envelope begins to break down. During metaphase, the chromosomes align in the center of the cell. http://www.macroevolution.net/prophase-ii.html
WebbThe interphase is divided into three phases; G 1 phase, the cell grows in size and makes necessary proteins in this phase. S phase, the cell undergoes DNA replication. G 2 phase, … WebbMeiosis I is differentiated into many phases, that is, prophase I, metaphase I, anaphase I, and telophase I. Prophase I is further divided into sub-stages: Leptotene: In this stage, the initiation of chromosome condensation takes place and it attains a composite form.

WebbProphase 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.
