The Generation-To-Generation Sequence of Stages in an Organism's Life History

Question

The generation-to-generation sequence of stages in an organism's life history is called (its)
A)alternation of generations.
B)pedigree.
C)F2 generation.
D)cell cycle.
E)life cycle.

Accepted Answer

The term "life cycle" refers to the sequence of stages that an organism goes through from birth to death (or reproduction). It includes all the stages of growth, development, reproduction, and aging that occur during an individual's lifetime. The other answer choices are not as appropriate because they either refer to specific terms in genetics (alternation of generations, F2 generation) or to a diagram of family history (pedigree) or a process in cell biology (cell cycle).
