Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Metaphase-1 of meioses are the pairs of chromosomes (bivalents) become arranged on the metaphase plate and are attached to the now fully formed meiotic spindle.
Prophase of mitosis
(i) It is a short phase and is not divided into any sub phase.
(ii) Pair formation in between homologous chromosomes does not occur as there is no attraction between than.
(iii) Chiasma is not formed.
(iv) Crossing over does not occur.
(v) Part exchange does not occur in the chromosome. So gene arranges not remains unchanged.
(vi) It has only one step.
Prophase-1 of meioses
(i) It is a long phase and is divided into the sub phases.
(ii) Pair formation (synapsis) due to attraction occurs in between homologous chromosomes.
(iii) Chiasma is formed.
(iv) Crossing over occurs.
(v) Part exchange occurs, which changes the gene arrangement of the chromosomes.
(vi) It Its two steps such as, prophase-1 and prophase-2.
