| The stages of meiosis | Meiosis I | Meiosis II |
Interphase | Set of chromosomes 2p. The same processes are observed as in mitosis, but more prolonged , especially with the formation of eggs. | A set of haploid chromosomes ( p ). There is no synthesis of organic substances. |
prophase | Longer lasting. At the beginning of the phase, the same processes as in mitosis. In addition, there is a conjugation of chromosomes, with K otoroma homologous chromosomes converge along the entire length and twist. In this case, genetic information can be exchanged (chromosome crossing) – crossing over. Then the chromosomes diverge. | Short; the same processes as in mitosis, but with p chromosomes. |
Metaphase | Further chromosome spiraling occurs , their centromeres are located at the equator. | The same thing happens as in T meiosis, but with p chromosomes. |
Anaphase | Centromeres are not divided. The bottom of the isomologous chromosomes, consisting of two
chromatid bonded by common centromere . |
The same thing happens as in T meiosis, but with p chromosomes. |
Telophase | It doesn’t last long. Homologous chromosomes enter different cells with a haploid set of chromosomes. The cytoplasm is not always divided. | Cytoplasm is divided. After two meiotic divisions, 4 cells with a haploid set of chromosomes are formed. |
