Created by StemPy LabAssertion (A): In the oocytes of some vertebrates, diplotene can last for months or years. Reason (R): During diplotene, the synaptonemal complex dissolves, and the recombined homologous chromosomes tend to separate from each other except at the sites of crossovers.

← Read the following statements about meiosis.
(i) In metaphase I, the bivalent chromosomes align on the equatorial plate.
(ii) In anaphase I, the sister chromatids separate and move to opposite poles.
(iii) In metaphase II, microtubules from opposite poles attach to the kinetochores of the sister chromatids.
(iv) Anaphase II begins with the simultaneous splitting of the centromere of each chromosome.
(v) Telophase I is followed by cytokinesis, which gives a dyad of cells.
(vi) At the end of meiosis II, four haploid cells are formed.
