Meiosis & Genetic Variation
DESCRIPTION
Before meiosis begins, DNA has been replicated. Each chromosome consists of two sister chromatids joined at the centromere. The cell is diploid (2n).

Mitosis Phases
Step through all 6 phases of the cell cycle: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis. Each phase features a Canvas 2D cell animation, key events list, DNA content tracker, and chromosome count. Use Auto Play to watch the full cycle.
Cell Membrane Transport
Simulate four types of membrane transport: simple diffusion, facilitated diffusion, active transport (ATP-powered), and osmosis. Adjust inside/outside concentrations and watch particles move across an animated phospholipid bilayer. ATP pump and channel proteins are rendered for each mode.
Enzyme Kinetics
Visualize Michaelis-Menten kinetics with an animated enzyme-substrate particle scene, a live V vs [S] curve, and a Lineweaver-Burk double-reciprocal plot. Adjust Vmax, Km, and highlighted [S]. Switch between no inhibitor, competitive (↑Km, Vmax same), and noncompetitive (↓Vmax, Km same) to see how each changes both graphs in real time.
Mendelian Genetics
Interactive Punnett square builder with four cross types: monohybrid (3:1), dihybrid (9:3:3:1), testcross (1:1), and incomplete dominance. Select parent genotypes via dropdowns to regenerate the square and ratio donut chart instantly. Simulate 100 offspring to compare empirical vs expected ratios. Color-coded cells distinguish dominant, heterozygous, and recessive genotypes.
