Expression profiles for six zebrafish genes during gonadal sex differentiation

Table 2 Ratio between genes with expected sex-related expression

	Ratio	Average	± Std
Expected females		118.51	98.01
Expected males	$\frac{(f i g α \times c y p 19 a 1 a)}{(d m r t 1 \times s o x 9 a \times a r)}$	1.12 × 10^-7	2.08 × 10^-7
Female gonad		8.54 × 10¹⁶	3.65 × 10¹⁵
Male gonad		7.49 × 10^-16	5.13 × 10^-17
Expected females		2.18	3.70
Expected males	$\frac{f i g α}{d m r t 1}$	0.002	0.003
Female gonad		11995.65	3061.41
Male gonad		0.017	0.0044

The calculated ratios of expected females and expected males are based only on data from the 56% of the investigated fish that showed expected "male" or "female" expression pattern for all five genes (fig α, cyp19a1a, dmrt1a, sox9a and ar). The ratios of female gonad and male gonad are based on adult fish.
