Mitosis: Chromosome Segregation & Cytokinesis (2D)

2D mitosis lab: interphase through cytokinesis with a probabilistic nondisjunction model — set chromosome-pair count, division speed and error rate, then read live per-cycle daughter-cell chromosome counts.

This 2D companion runs the same five-phase mitosis cycle as the 3D version — interphase, prophase, metaphase, anaphase, telophase & cytokinesis — through a flat, side-on canvas view built for reading the mechanics rather than orbiting a scene: a control panel exposes division speed, chromosome-pair count and a nondisjunction error-rate probability, spindle fibers are drawn as straight lines from two fixed poles to every chromosome, and at the end of each cycle the live readout reports exactly how many chromosomes each of the two daughter cells ended up with. Push the error rate above zero and, on roughly that fraction of cycles, one pair fails to separate — both sister chromatids get pulled to the same pole — so one daughter finishes with an extra chromosome and the other with one fewer, a directly countable aneuploidy readout rather than an implied one.

⚙ Under the hood

Five-phase mitosis state machine (interphase → prophase → metaphase → anaphase → telophase/cytokinesis) with a per-cycle probabilistic nondisjunction model, live phase progress, cycle count and daughter-cell chromosome-count readouts.
