Relative expression of gsdf and inha in germ cell-free and wild type gonads. Expression of gsdf a, b and inha c, d relative to EF1α, in GCF and two stages of WT ovary a, c and testis b, d of Atlantic salmon, measured by qPCR. All values were calibrated to the average ΔCt of the immature WT group. The data are shown as mean with SEM (N = 9–24 individuals). Different letters represent significant differences between groups (p < 0.05). GCF, germ cell-free; WT, wild type
