Comparison of FCC's of genes in turbidostat competition to dosage compensation. Only the genes studied by Springer and co-workers  are shown. A. The overlap between HFC genes in turbidostats and genes with compensation or exacerbation is not significant. B. No significant correlation (Spearman rho = 0.016, p-value = 0.69) can be found between dosage compensation and FCC'. (Note: Correlation of FCC' to dosage compensation reported by Torres and co-workers'  is rho = 0.01, p = 0.83).
