(a) Per generation changes in the frequency of HI during 10 generations of experimental evolution, when HI was started as being either the more common or the rarer haplotype. (b) The estimated strength of frequency dependent selection (SI) on mtDNA haplotypes over 10 generations, where positive values correspond to negative frequency dependency. Selection on mtDNA haplotypes was overall negatively frequency dependent, although those lines where HI was initially rare and that simultaneously experienced a more heterogeneous resource environment showed little evidence of selection. Given here are mean values (±SE) across lines (red: homogenous environment; blue: heterogeneous environment)
