In this lab, students experiment with genes and environment for a population of toothpick “fish”.
They should have an understanding of basic genetics (genotype & phenotype) before this activity. Concepts covered include: genetics review, biodiversity & populations reacting to environmental pressure, introductory evolution (I use this as a bridge from a genetics unit to an evolution unit).
Supplies needed: (per group)
1 “gene pool” container (a cup)
8 green toothpicks
8 red toothpicks
8 yellow toothpicks
