Lab 15: Population Genetics
45.5% (=91/200). Note that the dominant gene is less prevalent
than the recessive gene. This is not unusual, it is important to
remember that dominance has no direct relationship to prevalence.
Questions
1. What is the gene pool of this population?
2. What is the gene frequency?
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:
Fact: Both populations contain the same 4 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.
NOTE: In these exercises on gene
pool, gene frequency and genetic
diversity; assume there are 4 alleles
for color and that all butterflies are
homozygous.
