Chromosomes and meiosis study guide
Web22. There will be two divisions in meiosis. Homologous chromosomes separate in the first division of meiosis I. Sister chromatids separate during meiosis II. 23. Study the chromosomes in anaphase I and telophase I carefully. Three chromosomes remain in each cell at the end of the first meiotic division. The resultant daughter cells are haploid. 26.
