Delayed follicle activation and puberty onset in activin βA double mutant (inhbaa-/-;inhbab-/-) at 45 dpf.
In control (inhbaa+/-;inhbab+/-) and single mutant (inhbaa-/-, inhbab-/-) fish, PV follicles with cortical alveoli in the oocyte started to appear when their BL and BW reached the threshold for puberty onset (1.80 cm/100 mg). However, in the double mutant (inhbaa-/-;inhbab-/-), PV follicles did not appear in many individuals although their body size had reached the threshold. The BL (cm) and BW (mg) of each fish are shown on the top. The asterisk shows PV follicles. PG, primary growth stage.
