Document Summary
A population of grass is spreading out of control in southern california. A scientist studying this grass is trying to determine if the population is evolving and if the grass is likely to slow its spread as time passes. She determines that traits found in the current generation of grass individuals (size, seed number, etc) are predictably passed to offspring generations. Grass individuals with higher seed numbers have more surviving offspring in the following generation. Genetic studies indicate that all the grass individuals tested are genetically identical. A no, because traits are not heritable for this species. B yes, because the grass is spreading so quickly. C yes, because certain traits (like high seed set) lead to increased reproduction. D no, because there is no genetic variation in the population. E you cannot tell until multiple generations have passed: the wings of an ostrich, the pelvis of the whale, and the human appendix are all examples of:
