Meiosis

HideShow resource information
Chromosomes supercoil and come together in homologus pairs to form a bivalent, chromatids wrap around each other at chiasmata.
Prophase 1
1 of 8
Centromeres attach to spindle fibres and bivalents arrange themselves along the equator
Metaphase 1
2 of 8
Each one of the homologus pairs is pulled apart by the spindle to opposite poles
Anaphase 1
3 of 8
The nuclear envelope reforms around the chromosomes at each pole
Telophase 1
4 of 8
The nuclear envelope breaks down again, chromosomes supercoil and spindle fibres form
Prophase 2
5 of 8
Chromosomes arrange themselves on the equator of each cell and are attached to the spindle by their centromere.
Metaphase 2
6 of 8
The centromeres divide and chromatids are pulled to opposite poles by the spindle fibres and randomly segregate.
Anaphase 2
7 of 8
A tetrad of four haploid cells is formed as cells divide by cytokinesis and nuclear envelope reforms
Telophase 2
8 of 8
