Chromatid chromosomes "raise" together

Models allowing to represent the following processes:
- the behavior of chromosomes during mitosis
- the behavior of chromosomes during the formation of reproductive cells and the zygote
Chromosomes or chromatids are represented by magnetic rods of different colors and sizes.
Genes or alleles can be schematized according to the desired uses, either with a dry-erase marker or with a permanent marker to keep annotations from one class to another.
The cell wall is represented by flexible bands allowing to simulate cytoplasm division.
The chromatids are attached to each other thanks to an invisible magnetization system, at the centromere level.

This set consists of
- 14 sticks: Long autosomes: 4, Short autosomes: 4, X chromosomes: 4, Y chromosomes: 2
- 2 cell outlines
Supplied with a detailed manual with photocopiable support.
