Fig. 2

Replicated lines of D. subobscura were founded with flies carrying either mtDNA haplotype HI or HII in different proportions. This figure shows the mean frequency (±SE) of haplotype HI within lines during the course of experimental evolution. Haplotype I increased in frequency when rare and decreased in frequency when common, providing evidence for overall negative frequency dependent selection (red: homogenous resource environment; blue: heterogeneous resource environment)
