Transcript levels among mtDNA-mtRPOL genotype classes for mitochondrial and nuclear genes. Mean gene expression measures in hypoosmotic stress treatment only shown for each gene and cross with respective standard error (all values = cDNA copy number x10⁵). Mitochondrial gene expression values (left column) are presented, left to right, as COI, CytB, and ATP6; nuclear gene expression values (right column) are presented, left to right, as COVa, CytC, and ATPc. AB = Abalone Cove; SCN = Santa Cruz; SD = San Diego.
