Figure 4From: Quantitative trait locus mapping of genes associated with vacuolation in the adrenal X-zone of the DDD/Sgn inbred mouseAllelic contributions to QTLs for the X-zone vacuolation grades for F 2 non-Aymice ( A–D ). Homozygous DDD alleles are represented by DDD/DDD, homozygous B6 alleles by B6/B6, and heterozygous alleles by DDD/B6. The Y-axes show the mean grade scores and the error bars are SE’s.Back to article page
