|It occurs in all somatic cells and may
persist all over life
|It occurs in reproductive cells at
|It involves a single division, which
leads to two daughter cells only.
|It involves two successive divisions,
which leads to four daughter cells.
|Consequent mitotic divisions are
similar to the previous ones.
|Two meiotic divisions are dissimilar,
the first is reductional while
the second is equational.
|Prophase is relatively short and simple.||Prophase I is very long and elaborate, which comprises
five subphases like leptotene, pachytene,
zygotene, diplotene, and diakinesis.
|There is no pairing of homologous chromosomes.||Homologous chromosomes pair and often
undergo crossing over in prophase I.
|Chromatids are genetically similar to
the chromosomes they arise from
|Chromatids may vary genetically from the chromosomes
they emerge from because of crossing over.
|No synaptonemal complex formed.||Synaptonemal complex forms among
synapsed homologous chromosomes.
|Chromosomes do not unfold, and no protein
synthesis and transcription take place in prophase.
|Chromosomes unfold, n and protein synthesis
and transcription may take place in diplotene
of prophase I (oocytes of specific animals).
|Daughter cells have a diploid number (2N)
of chromosomes like the parent cell.
|Daughter cells have a haploid number
(N) of chromosomes, unlike the parent cell.
