Table 1. Embryonic viability and frequency of male self-progeny of various mutants.

Genotype	Embryonic Viability	Frequency of male self-progeny
wildtype	100%	0.1%
pch-2(tm1458)	100%	0.7%
mnDp66/+;meDf2/+	97.5%	11.6%*
mnDp66/+;meDf2/+;pch-2(tm1458)	98.2%	0.9%*
ced-4(n1162)	90.8%	0.2%
ced-4(n1162);pch-2(tm1458)	75.7%	0.2%
htp-3(vc75)	100%	0.1%
htp-3(vc75);pch-2(tm1458)	81.9%	1.1%

*Counts of male self-progeny were corrected based on the expectation that 12.5% of male progeny and 6.25% of hermaphrodite progeny of these animals are inviable.
