Before beginning this lab, be sure to review the lab introductions.
: In the following experiments on gene pool, gene frequency, and genetic diversity, assume
there are four alleles for color and that they are all homologous.
Experiment 1: Genetic Variation
is simply the genetic difference within or between populations observed either
in the gene pool or in the gene frequency.
Consider the following two populations of butterflies (Figure 1):
Figure 1: Butterfly Populations
: Both populations in Figure 1 contain the same four colors
(yellow, orange, white,
and orange/white combo) of butterflies, thus the gene pool is the same. However, the
of colors within that population is different. As a result, their gene frequencies
different, resulting in genetic variation between the two populations.
In this experiment, you will create two different populations and investigate their genetic
