Question
Transcribed Image Text:Serpentine soils are a particular soil type dominated by an elevated concentration of certain ions and
metals. It is distributed in a meandering fashion (giving it its name), with abrupt boundaries to the
more typical sandstone soils. The high concentration of these metals is generally toxic to many
plants. However, populations of Leptosiphon parviflorus with pink flowers have managed to grow and
reproduce on these serpentine soils in northern California. In addition, L. parviflorus plants with white
flowers and separated by only a few meters occur on the sandstone soils.
You performed an experiment that measures differences in survival (fitness) when seeds from
sandstone and serpentine soil are grown in both environments. The results from this experiment are
presented in this graph:

Explain why you cannot conclude from this graph that the observed flower color differences in
nature are under genetic or environmental control. What would you need to know in order to draw
such a conclusion?
