Fig. 3: Standard length and body condition across inversion genotypes and salinity treatments.

The estimated marginal means and 95% confidence intervals for standard length and body condition from linear mixed models are shown across the three chromosomal inversions. FW denotes individuals homozygous for the freshwater-prevalent inversion orientation, HET denotes heterozygous individuals, and M denotes individuals homozygous for the marine-prevalent inversion orientation. Data are jittered within genotype classes to better show the confidence intervals for each treatment. These results are based on the data across the three replicate families for each inversion. Sample sizes and statistical analyses are shown in Table 2. The effects of sex are shown in Fig. S1.
