Meiosis: The Process. Biology 12. Cartoon of the day:. Context: . Meiosis allows for the formation of sperm and egg cells. Overview:. Interphase Meiosis I Prophase I Metaphase I Anaphase I Telophase I (and cytokinesis) Meiosis II Prophase II Metaphase II Anaphase II
for the formation
of sperm and
Alignment is random so that chromosomes from one will be mixed with the other parent when they move apartMeiosis I: Metaphase I
**Remember in mitosis, it was the chromatids that separated, not pairs of chromosomes!Meiosis I: Anaphase I
The cell begins to divide into two daughter cells. of the cell.
Each cell produced after cytokinesis has been reduce from diploid to haploid.Meiosis I: Telophase I (and cytokinesis I)
DNA is not replicated before meiosis II
Nuclear membrane begins to dissolve of the cell.
Spindle fibers begin to formMeiosis II: Prophase II
Spindle fibres attach to centromeres of the cell.
Sister chromatids line up at equatorMeiosis II: Metaphase II
Centromeres divide in two of the cell.
Spindle fibres pull sister chromatids towards opposite ends of cell (pole)Meiosis II: Anaphase II
Nuclear membrane reforms and cytoplasm divides of the cell.Meiosis II: Telophase II and (cytokinesis II)
