Neutral mean F_st is calculated from loci in Machado et al. (2007). Values in parentheses represent the standard deviation. For individual loci and and subspecies, we determined whether F_ST values were significantly different from the neutral distribution using a Z-test. Furthermore, we compared the distribution of F_ST values between neutral and FRP loci using a two-sample t-test. All F_ST values were calculated in DnaSP (Rozas et al. 2003). wr., D. m. wrigleyi; ba., D. m. baja; so., D. m. sonorensis; mo., D. m. mojavensis. *P < 0.05, **P < 0.01, ***P < 0.001.

^aValues that remain significant after a conservative Bonferroni correction for multiple measures.
