WebMeiosis I - Key Takeaways. Meiosis I consists of fours stages: prophase I, metaphase I, anaphase I, and telophase I plus cytokinesis. Known as the reduction division, meiosis I produces two daughter cells, each with half the chromosome number of the parent cell and its copies (n + n). During prophase I of meiosis, the homologous chromosomes ... Web17 jun. 2016 · Meiosis is the type of cell division that produces gametes. It involves two phases of cell division to produce four haploid cells. Meiosis 1 consists of Prophase 1 - Homologous chromosomes pair up and crossing over occurs which is vital for genetic variation. Metaphase 1 - The paired chromosomes lined up in the middle of the cell.
Web8 aug. 2024 · At the end of meiosis I, there will be 2 haploid daughter cells, one with n+1 and the other with n-1. Both of these daughter cells will then go on to divide once more in meiosis II, producing 4 daughter cells, 2 with n+1 and 2 with n-1. Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II.
