The time it takes for a population to double in number is called the ______ time.

Explanation:
Generation time is the interval between when one generation is born and the next generation is born; for populations that grow by doubling each generation, this period corresponds to the time it takes for the population to double. In contexts like bacterial growth, generation time is a standard way to express how quickly a culture increases in size. Doubling time is a related phrase that describes the same idea—how long until the population becomes twice as large—but generation time emphasizes the generational turnover. The other terms—reproduction describes the act of producing offspring, and growth is a broader, less precise concept of increase.
