Table 1. Fertility of Gsr^-/- mice.

Sex		Gsr+/+	Gsr+/-	Gsr-/-	Total
Combined	Expected	59.25	118.5	59.25	237
	Observed	71	102	64	237
Male	Expected	31.75	63.5	31.75	127
	Observed	34	58	35	127
Female	Expected	27.5	55	27.5	110
	Observed	37	44	29	110

The observed numbers for male and female mice of the three genotypes shown in the table were obtained from heterozygous intercrosses. The Expected numbers were calculated based on the Mendelian inheritance. The Chi-Square tests results are: Combined, X(2) = 5.0084, p = 0.0817; Male, X(2) = 0.9685, p = 0.6162; Female, X(2) = 5.5636, p = 0.0619.
