**Figure 1. **Expression of *Myo7a* in the retina for the B6 and D2 parental strains, F1 hybrids, and 52 BXD lines. Expression for each strain (four mice per
strain) was generated using the RMA method and the Affymetrix Expression Console Software and normalized using modified Z-scores.
The x-axis denotes the strain while the y-axis denotes the mean expression given in a log2 scale. Each bar shows the mean
expression values ± standard error of the mean (SEM).
