Hierarchal clustering of candidate gene expression pattern in 7 Muscles. Columns for the seven muscles were fixed and rows representing gene expression were subject to clustering. The fold change of transcript abundance for the ratio of callipyge to normal was transformed to log2. The color scale for this heat map is red-orange-yellow, where the red indicates the magnitude of the fold change in callipyge is higher than normal and yellow represents gene expression was lower in callipyge than normal muscle. Significant differences are indicated by (*P<0.05, **P<0.005 and ***P<.0005) between callipyge and normal lambs within each muscle
