WebbIn meiosis I, the phases are analogous to mitosis: prophase I, metaphase I, anaphase I, and telophase I (below figure). Meiosis I proceeds directly to meiosis II without going through interphase. Meiosis I is unique in that genetic diversity is generated through crossing over and random positioning of homologous chromosomes (bivalent chromosomes). WebbProphase of meiosis I is the signature event of the meiotic process, since it is here that genetic recombination takes place. Prophase is complex and is subdivided into five …

WebbDescribe the steps of meiosis I. Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis.

WebbFinal answer. 12. Meiosis has two stages - Meiosis I and Meiosis II. Monday, we reviewed both of these stages. Meiosis I looks just like mitosis, the phases (here we label these as Prophase I, Metaphase I, Anaphase I, and Telophase I) are the same too and so are the results -2 daughter cells (diploid) are made from 1 cell (diploid). Meiosis II ... Webb14 juli 2015 · Patty Belloise. 11 1. Centrioles migrate to opposite poles at the end of meiosis and then the centrioles duplicate in the new cell and during the S phase. One centriole grows from the parent centriole. Therefore, like in DNA replication the centriole replication is semi-conservative. – Patty Belloise.
