🧪 Conservation Genetics Simulation

Conservation genetics turns on one deceptively simple idea: a population's census size and its effective size (N_e) are rarely the same number, and it is N_e — not the number of animals you can count — that governs how fast genetic diversity erodes. This simulator renders a breeding population as a live 3D cloud of individuals, each carrying one of several marker alleles, and lets you skew the sex ratio and the variance in offspring number while holding census size N fixed. Watch N_e fall away from N, the colour diversity of the population converge generation by generation, and the measured gene-diversity curve track the textbook decay formula H(t) = H₀·(1 − 1/(2N_e))^t in real time — with the classic 50/500 rule flagging when the population has drifted into the danger zone.
