WebThe zygospore may stay dormant for long periods of time, but under the right conditions, the diploid nuclei undergo meiosis to make haploid nuclei that are released in single cells called spores 4 ^4 4 start superscript, 4, end superscript. Because they were formed through meiosis, each spore has a unique combination of genetic material. WebOct 10, 2024 · A cell can then go through meiosis I, the first division, and meiosis II, the second and final division. A cell goes through multiple stages twice as it progresses through both divisions of meiosis: prophase, metaphase, anaphase, and telophase. At the end of meiosis I, the parent cell splits into two daughter cells.
