Question

Quizplus · Accepted Answer

The high rate of the autosomal dominant disorder, Moonophilia distractens, among the descendants of the eight space travelers suggests that the disorder may have arisen due to a founder effect. This is because the initial population on Zebulon was derived from a small number of founders (eight people) carrying a specific genetic variation. Over time, due to random genetic drift, the frequency of the mutated gene increased among the descendants, leading to a high prevalence of the disorder. A founder effect is a result of genetic isolation and small population size, and can result in the fixation of genetically distinct traits in a population.
