a researcher is studying a rodent species with a lot of variability in tail length. individuals may have short tails, medium tails, or long tails. the researcher has noticed that a new invasive predator, which catches prey by their tails as they try to escape, seems to catch individuals with long tails more often than those with short tails. based on a small field trial, the relative fitness of long-tailed individuals seems to be 0.6 compared to short-tailed ones (1.0), with medium tails in-between (0.8). use the examples tab to predict the outcome after selection for the rodent in regions with the invasive predator. what describes the population after 100 generations of selection? choose all that apply
