Table 2 . sao-1(ok3335) suppresses embryonic morphogenesis defect of weak aph-1 alleles.

Genotype of mother	% embryos with successful body morphogenesis (n)
	sao-1(+)	sao-1(ok3335)
aph-1(zu147)	89 (767)	97 (325)
aph-1(zu123)	0.82 (968)	20 (712)
aph-1(ep140)	0 (401)	0 (445)
aph-1(or28)	0 (315)	0 (452)

Embryos were collected from at least 10 mothers that were homozygous for either sao-1(+) or sao-1(ok3335) and also homozygous for the indicated aph-1 allele; all animals were also homozygous for unc-29(e1072). n, number of embryos scored. Embryos were scored as having successful body morphogenesis if the hypodermis successfully enclosed the embryo and elongation proceeded; see Figure 1 for representative embryos.
