ANALYZING DATA. You study males in populations of a certain species of minnows in a series of lakes at different latitudes. You find that they exhibit clinal variation in average weight at maturity and hypothesize that the weight differences are due to genetic factors. You predict that the average weights at maturity of representatives of each population reared in aquaria will differ in ways that are consistent with the differences you observed among the wild populations. However, when you conduct the experiment, you find no differences among the population averages. What is your conclusion
