Mitosis: Chromosome Segregation & Checkpoint Failure (2D)

2D mitosis lab: prophase through cytokinesis with real cell-cycle timing, spindle-fiber mechanics pulling sister chromatids apart, and an adjustable spindle-assembly checkpoint you can weaken to trigger nondisjunction and watch aneuploid daughter cells form.

This 2D companion drives the same mitotic process as the 3D version — prophase condensation, metaphase congression, anaphase separation, telophase decondensation and cytokinesis — through a plain canvas view built around the actual mechanics rather than a scene to orbit: real relative phase timing scaled by a cell-cycle-speed slider, an adjustable chromosome count, and a spindle-assembly-checkpoint stringency control that, when weakened, lets a chromosome slip past uncorrected so both sister chromatids get pulled to the same pole, producing visibly aneuploid daughter cells you can read off directly in the live chromosome-count readout.
