Four times as much genetic material is present in a cell during prophase I compared to a cell that has competed meiosis II. Prophase I is a phase in the first stage of meiosis (meiosis I). During this phase, chromosomes become visible. cross-over occurs, the nucleolus disappears, the meiotic spindle forms and the nuclear envelope disappears. The genetic materials in prophase I divides into two at the end of meiosis I forming tow daughter cells, which then divides again into two at the end of meiosis II forming four daughter cells.
Helps reduce the chances of developing chronic diseases that can last a lifetime,also can improve the quality of your life.
