Cytokinesis. - 2Interphase.- G1 - All organelles are replicated.
- S - DNA replicated, producing sister chromatids. Centrioles duplicate. Chromatids condense.
- G2 - All enzymes are replicated. - 3Prophase I.- Homologous pairs of chromatids lie side by side in a process called synapses, forming a bivalent.
- 4Prometaphase.- Meiotic spindle is fully formed.
- Sister chromatids attach to spindle fibres.
- Both sister chromatids are attached to one spindle fibre. - 5Metaphase 1.- Bivalents randomly align themselves along the metaphase plate, this adds to genetic diversity.
- 6Anaphase I.- Homologous chromosomes separate and move towards opposite poles.
- 7Telophase I.- Chromosomes de-condense.
- Nuclear envelope reforms. - 8Cytokenisis.- Separates the cells with the help of the cleavage furrow.
- 9During the transaction from meiosis I to meiosis II.........- Centriole duplicates, moving to opposite poles.
- 10Prophase II.- Sister chromatids condense.
- Spindle fibres form.
- Nuclear envelope disintegrates. - 11Prometaphase II.- Sister chromatids attach themselves to the spindle fibres
- 12Metaphase II.- Spindle fibres align the sister chromatids along the metaphase plate.
- 13Anaphase II.- Sister chromatids separate individual chromosomes towards opposite ends of the poles.
- 14Telophase II.- Chromosomes de-condense.
- Nuclear envelope forms. - 15Cytokinesis.Cleavage furrow separates the two diploid cells into four haploid cells.
