Explain diakinesis of meiosis I division

Diakinesis of meiosis I: (a) The bivalents become condensed to the maximum. These are evenly distributed throughout nucleus.
(b) Nucleolus is detached from its chromosomes and disappears.
© The centromeres of bivalents repel each other and the chiasmata move laterally.
(d) As a result, the paired chromosomes are united only at the ends. This process is known as the “terminalization”.
(e) In big sized chromosomes with many chiasmata, terminalization is never complete.
(f) They remain joined together until metaphase-I. Nuclear membrane is broken into pieces and disappears then.
(g) Bivalents lie evenly distributed in cytoplasm
without overlapping among them. .
(h) For counting the chromosome in sexually
reproducing organisms, it seems a best stage of cell division.
