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:
Descriptive research
Explanation:
If our goal is to estimate the prevalence of a disease or exposure in a population, we are talking about descriptive research. Whenever we are trying to describe the characteristics of a population or a phenomenon (in this case the frequency of a disease and exposure to it) we are doing a descriptive study. The results of this type of studies are usually represented in descriptive statistics and percentages. For example, from this sort of survey we would find out the percentage of population that suffer this disease.
