A species of Petunia is found to behave as an annual at site 1 and as a perennial at site 2. To explain why these differences in life history strategy exist in the different environments, an experiment is performed where seeds from both sites are collected and planted in both environments. Fitness data on survival and fecundity are shown below: annual seeds grown in site 1 perennial seeds grown in site 1 annual seeds grown in site 2 perennial seeds grown in site 2 0.04 0.04 juvenile survival 0.04 0.04 40 20 20 20 birth rate adult survival 0.0 0.1 0.0 0.3 What would be the expected outcome at each site if a mutation occurred that resulted in a doubling of per capita birth rates in the perennial seeds?
