Data Representation: A genetic-drift model predicts that random allele-frequency changes are larger in small populations than in large populations. After 20 generations, five small populations had changes of 0.31, 0.44, 0.27, 0.38, and 0.52. Five large populations had changes of 0.04, 0.07, 0.03, 0.06, and 0.05. Which appraisal is most justified?
