Class 10 Botany simulations · Heredity

Natural selection on a trait

Apply stabilising, directional or disruptive selection to a population and watch the trait distribution change.

Open the simulation

What to notice

Industrial melanism in peppered moths is a classic example of directional selection.

Key relation

Fitness differences + heritable variation → change across generations

Try this

Choose directional selection and run 20 generations.

What you can change

• Selection: choose Stabilising, Directional, Disruptive
• Generations: 0 to 30

More in Heredity

• Dihybrid cross: independent assortment
• Mendel’s monohybrid cross
• Sex determination and X-linked traits
