Ovarian mRNA expression levels of steroidogenic enzymes CYP11A1 (A,B), CYP17A1 (C,D), and CYP19A1 (E,F) in five-month-old female alligators following FSH challenges (50 ng/gram BM daily) of two (A,C,E) and five (B,D,F) days duration: vehicle control treatments (Veh) or follicle stimulating hormone treatments (FSH). Bars report mean ± SEM and shading denotes animals hatched from eggs collected from: closed bars = Lake Apopka and open bars = Lake Woodruff. All mRNA expression sample means are normalized using 18S ribosomal expression levels. Horizontal lines with capitol letters over bars denote indicate statistical significance by treatment. Brackets with lower case letters above bars indicate lake of origin statistical significances.
