They then measured the percentage of male and female parent birds that survived the following winter. (Both males and females provide care for chicks.)

Imagine that you are managing a large ranch. You know from historical accounts that wild sheep used to live there, but they have been extirpated. You decide to reintroduce them. After doing some research to determine what might be an appropriately sized founding population, you do so. You then watch the population increase for several gen- erations, and graph the number of individuals (vertical axis) against the number of generations (horizontal axis). The graph will appear as
