WebChromosomes are arranged at the spindle equator during the metaphase stage. During metaphase I, the homologous chromosomes are paired so that bivalents are arranged at the equator. These bivalents are comprised of four chromatids, these bivalents are present in a single cell. Meiosis I produces two haploid cells which undergo meiosis II. WebSolution Verified by Toppr Correct option is B) Chromosomes are the shortest and thickest during metaphase. It is the stage in which nuclear envelope disappears completely so that nucleoplasm comes in contact with cytoplasm. Chromosomes are arranged at the equator and form a sort of metaphasic plate. So, the correct answer is option B.
