During the critical preparation for chromosome separation in meiosis, the physical nature of the DNA and its relationship to its packing with histones and other proteins is dramatically altered.

In which of the following links is there a description of this early stage, when the physical nature of the pre-division chromosomes is dramatically altered?

During at least part of meiosis, homologous chromosome pairs are held together, at a critical stage, by a mysterious structure called the 'synaptonemal complex'.

In which of the following links is this 'complex' shown and it purpose described?

Just before the complicated complex of chromatids and DNA molecules becomes attached to the spindle fibers in meiosis, the "spot welds" that hold the parts of the complex together all move to the ends of the chromosomes. It is not known why.

In which of the following links is this final preparation stage illustrated and described?

Once all the chromosomes and chromatids have been separated into different areas of the meitotically dividing cell, the fate of the haploid collections of biological information can be very different.

In which of the following links are the various outcomes of a single meiosis illustrated?
