(A,B) Delta Ct method values for head (A) and body (B) samples. Bars depict mean standard deviation of the differences in the paired comparisons of each gene in each sample (level of deviation). Ranking the reference genes from more stable (left) to less stable (right). (C,D) Bestkeeper method values for head (C) and body (D) samples. Bars depict Bestkeeper- stability value ranked according the crossing point standard deviation value (Std dec [+− CP]. Ranking the reference genes from more stable (left) to less stable (right). (E,F) Normfinder values for head (E) and body (F) samples. Bars depict Normfinder- stability value ranking reference genes according to the lowest intra- and intergroup variation. Ranking the reference genes from more stable (left) to less stable (right).
