Allele Frequencies & Natural Selection
by Anonymous
Use allele frequency p to build genotype ratios, then change selection pressure, generations, and population size to see how frequencies shift and fluctuate.

About this app
An interactive high school biology simulator for exploring allele frequencies, genotype proportions, natural selection, and genetic drift. Adjust dominant allele frequency p to see AA, Aa, and aa proportions calculated as p², 2pq, and q², then compare how selection pressure, generations, and population size change allele frequencies.
Use cases
- High school biology students studying allele frequencies
- Teachers demonstrating Hardy–Weinberg genotype proportions
- Learners exploring how selection pressure changes recessive allele frequency
- Classroom experiments on population size and random frequency fluctuations
Features
- Interactive p control with AA, Aa, and aa proportions
- Natural selection simulation across multiple generations
- Selection pressure levels from none to lethal
- Population-size controls showing the expected range of random fluctuation
- Guided missions with reset and next-step controls
