Comparing nuclear and chromosomal activities in mitosis and meiosis:

	Mitosis	Meiosis
Synapsis	does not occur.	Occurs during prophase-1.
Crossing over	does not occur.	Occurs during prophase-1.
When centromeres seperate	Occurs during anaphase.	Occurs during anaphase-2.
Chromosome structure and movement during anaphase	V-shaped and move towards poles.	Breakdown of chiasmata and move towards poles.
Number of divisions	No division in number of chromosomes.	Division of chromosomes in anaphase-1.
Number of chromosomes in daughter cells	No reduction in chromosomal number.	Reduced to half.
Genetic similarity of daughter cells to parent cells	Genetically similar to parents.	Genetically dissimilar to parents.

To simulate Prophase of Meiosis I - Synapsis and Crossing Over: 1. Homologous chromosomes come together and synapse along their entire length. This pairing (synapsis) of homologous chromosomes represents the first big difference between mitosis and meiosis. This pairing will produce two tetrads, each consisting of four chromatids. Entwine the two chromosomes to simulate synapsis. 2. To simulate crossing over, start with your long tetrad and transfer the circles on the red chromatid at the fourth bead or “gene” to...
