Fig. 4: Within taxa measures of population genetic structure for Clarkia concinna subsp. automixa, Clarkia concinna subsp. concinna, and Clarkia breweri collected from twelve populations across northern California.

Shown is the genetic differentiation between populations (left) and the first two axes of principal components analyses (right) of A C. concinna subsp. automixa (2 populations), C C. concinna subsp. concinna (4 populations), and E C. breweri (6 populations) collected across northern California. For the genetic differentiation bar charts, bars are individual ancestry assignment by the percent of assigned ancestry to each genetic cluster by ADMIXTURE. X-axis labels indicate population names. B, D, F First two axes of the PCAs where each point is an individual and colors represent assigned genetic cluster from ADMIXTURE. The percent variation explained by each axis is denoted in parentheses.
