Answer: Genetic Drift
Explanation: Genetic drift is an evolutionary mechanism whereby gene or allele frequency of a particular population change over generations due to random chance. The effect of genetic drift is most visible in small population due to reduction in population size resulting from natural disaster or splitting of a small group from the main population to formation a colony. However, it can occur in large population as well but it's effect is as strong as that occurring within a small population.
The genetic drift among the Dunkers could be attributed to the official split between conservatives and progressives members in 1882.

Answer:
Check Explanation.
Explanation:
So, the question is about a research or an experiment on whether the intake of cola causes a lot of or severe headaches. And I will be using myself as the control experiment. Please note that I just did not want to use myself as the control experiment but because the question ask us to. That is the use of "single case design" which means that the person performing the experiment must use himself or herself as the control experiment instead of using another person.
Step one => I will make sure to know how often or how many times I do do get headaches.
Step two => I will then stop taking the cola, but after sometimes I will continue taking the cola back.
Using the single case design, I can test for my Hypothesis using the following steps;
For step two above, if during the period that I stopped taking cola, I did not have any headache and immediately I start taking the cola I started developing headaches, then
it is true that the artificial sweetener in the cola is responsible for the headaches.
To the second part of the question; I expect to find that that the artificial sweetener in the cola is responsible for the headaches.
My conclusion will be that the artificial sweetener in the cola is responsible for the headaches.
