Geographic profile of introgression from a deeper population sample. The Southern California population of C. immitis, which is more proximal to the range of C. posadasii, exhibits a greater incidence of introgression near the MEP4 locus than the Central California population (χ2 test; P = 0.01). The approximated ranges of C. immitis and C. posadasii are indicated with gray shading and hashing, respectively.
