Population Genetics Test Questions with Answers Explain how the Amish are an example of the founder effect. - Answer-The Amish population was established by a small number of individuals whose genetic diversity did not exactly match that of the distribution of genes in the general population. As a result, certain rare traits became more commonly expressed in the Amish population as it grew due to their over representation in the founding gene pool of the population. Explain how a bottleneck...
