Natural Selection Simulation
Inspired by PhET's Natural Selection β explore dominant/recessive traits, mutation, and environmental selection in a bunny population
π Equator
Generation: 0
How to Use
- The population starts with a single bunny β click Add a Mate so it can reproduce.
- The starting population is white fur, straight ears, short teeth (homozygous recessive:
ff ee tt). - Use Add Mutation to introduce a dominant allele (Brown fur, Floppy ears, or Long teeth) into one bunny β it will show the trait immediately and may be passed on.
- Choose an Environment and toggle βοΈ/βοΈ to change the ground colour, then switch on Selection Factors to see which traits help bunnies survive.
- Click Add 1 Generation or Play to advance β reproduction, inheritance, and selection all happen automatically each generation.
- Watch the Population by Generation graph to see which alleles become more or less common over time.
- Click Reset All to start over.
