Crime the sequence of event mitosis and meiosis first |
| Answer» Meiosis\xa0and\xa0mitosis\xa0both have prophase, metaphase, anaphase, telophase and cytokinesis.\xa0In\xa0meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the\xa0first division, called\xa0meiosis\xa0I. The daughter cells divide again in\xa0meiosis\xa0II, splitting up sister chromatids to form haploid gametes.\xa0The\xa0mitosis\xa0theory states that\xa0meiosis\xa0evolved from\xa0mitosis. According to this theory, early eukaryotes evolved\xa0mitosis first, became established, and only then\xa0did meiosis\xa0and sexual reproduction arise. | |
