Developmental assessment of GD18 fetuses from C57BL/6N × Sv/129 micea

Genotype n Fetal wt (% control) Crown-rump length (% control)
+/+ 23 100 ± 0 100 ± 0
+/− 25 102 ± 2 100 ± 1
−/− 16 70 ± 5* 86 ± 3*
a

GD18 fetuses were weighed, crown-to-rump measurements were obtained, and tails from fetuses were used for genotyping. Data are mean percentages of wild-type controls ± standard errors of the means. ∗, P < 0.05 by one-way analysis of variance.
