Note: In the following experiments on gene pool, gene frequency, and genetic
diversity, assume there are four alleles for color and that they are all
Experiment 1: Genetic Variation
Genetic variation is simply the genetic difference within or between populations
in the gene pool and/or gene frequency.
Consider the following two populations of butterflies (Figure 2)
Figure 2: Butterfly populations.
Assumptions: Both populations contain the same four colors of butterflies, thus
the gene pool is the same. However, the distribution of colors within that
population is different, thus their gene frequencies are different.

1. Pour 50 blue beads and 50 red beads into a 250 ml beaker. Without
looking, randomly take 50 beads from the 250 mL beaker and place them
in a 100 mL beaker (this is beaker #1).
2. Pour 50 green beads and 50 yellow beads into a second 250 mL beaker.
Without looking, randomly take 20 beads from the 250 mL beaker and
place them in the other 100 mL beaker (this is beaker #2).
Note: When done, return beads to their respective beakers (1 or 2) for use
in the next experiment.
1. What is the gene pool of beaker #1?
2. What is the gene pool of beaker #2?
3. What is the gene frequency of beaker #1?
4. What is the gene frequency of beaker #2?
5. What can you say about the genetic variation between these populations?
