Table 1.

Numbers of expected and observed E18.5 embryos and 21-day-old pups, total number of recovered neonates, and percentage viability of each genotype obtained by crossing heterozygous Sned1^WT/LacZ-Neo mice.

Sned1^WT/LacZ-Neo × Sned1^WT/LacZ-Neo	Sned1^WT/WT	Sned1^WT/LacZ-Neo	Sned1^{LacZ-Neo/LacZ-Neo}	χ² p-value
*Expected*	25%	50%	25%
E18.5	14 (27.5%)	22 (43.1%)	15 (29.4%)	0.607
Recovered neonates	74 (24.7%)	179 (59.6%)	47 (15.7%)
Alive at weaning (p21)	54 (26.7%)	130 (64.4%)	18 (8.9%)	<0.0001
Percentage viability	73.0%	72.6%	38.3%
