The Outcome:
Note: Triangle represents the frequency of slime-producing
individuals and Circle represents non slime-producing individuals.
As predicted, fish with the slime-producing trait increased in
frequency, while inversely, the non slime-producing individuals
decreased in frequency. As shown in the graph data, the slime
producing individuals started off at generation 1 with a
fairly low frequency of 5%, while the non slime-producing
individuals were 95% of the population. As we reach the 100th
generation, we see that the slime-producing fish have attained a
frequency of 90% of the population, while the non slime-producing
fish have decreased to 10% of the population.
We see that change in allele frequencies is fairly gradual, with the
"crossover" point occurring around the 26th generation. There are no
"sudden shifts" in the frequencies of the alleles. As we observe the
graph, we see that it took 100 generations for the slime-producing
allele to go from 5% of the population to 90%. This seems to suggest
that the non slime-producing allele was not enough of an
disadvantage to trigger an immediate "take over" from the
slime-producing fish.
