Average distance of the centrosome from the cortex upon first appearance in relation to symmetry breaking (SB) and extent of pseudocleavage (PC).

Centrosome- cortical distance (um)	WT	pam-1
All embryos	1.97 ± 2.27 n=36	1.71 ± 2.11 n=52 p=0.59
Embryos with SB	1.76 ± 1.90 n=35	1.63 ± 2.08 n=46 p=0.78
Embryos without SB	9.49 n=1	2.32 ± 2.42 n=6 p=0.61
Embryos with normal PC	1.66 ± 1.74 n=32	0.61 n=1
Embryos with weak PC	3.96 ± 4.04 n=2	1.64 ± 1.88 n=28 p=0.97
Embryos without PC	5.00 ± 6.36 n=2	1.85 ± 2.43 n=23 p=0.75

Distances were sorted into presence, absence, or weak pseudocleavage. Standard deviation is shown. No significant differences between pam-1 classes and wild-type (WT) embryos were found. P values were calculated by comparing WT all to pam-1 all; pam-1 SB classes to WT with SB; and pam-1 PC classes to WT with PC.
