During which phase of meiosis
Webprophase I Meiosis I. Compared to mitosis, which can take place in a matter of minutes, meiosis is a slow process, largely because of the time that the cell spends in prophase I. During prophase I, the pairs of homologous chromosomes come together to form a tetrad or bivalent, which contains four chromatids. WebDuring what stage of meiosis is genetic variation increased? By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells.Recall that the point of crossing over is to increase genetic diversity. If crossing over did not occur until sometime during meiosis II, sister chromatids, which are identical, …

Possible Answers: Metaphase I Prophase II Anaphase I Prophase I Correct answer: Prophase I Explanation: During prophase I homologous chromosomes will line up with one another, forming tetrads. During this lining up, DNA sequences can be exchanged between the homologous chromosomes.
WebJun 8, 2024 · During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Prophase II If the chromosomes decondensed in telophase I, they condense again.
WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
