Figure 2. The mean expression of Myo7a of BXD strains with the B allele and the D allele at the Myo7a locus. Among the 55 strains used, 33 have the B allele at the Myo7a locus, 19 have the D allele, and three are heterozygous. The values on the y-axis denote normalized expression levels on a log2 scale. There is a statistically significant difference in the expression of Myo7a among the strains carrying the B versus D alleles (p<0.0001).
