WebThe mitosis theory states that meiosis evolved from mitosis. [9] According to this theory, early eukaryotes evolved mitosis first, became established, and only then did meiosis and sexual reproduction arise. WebMeiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Before entering meiosis I, a …

WebIn 1876, a German zoologist Oscar Hertwig (1842–1922) first described the process of meiosis during his study of sea urchin eggs. His theory, which stemmed from the observation of two nuclei in one egg, stated that these nuclei most likely developed due to the integration of substances found within a spermatozoan and an egg.

WebMitosis steps consist of prophase, metaphase, anaphase, and telophase; the cell undergoes nucleus division and split into two identical daughter cells.
