a
Average number of embryos laid per worm ± SD.
b
M+Z– animals were the progeny of nT1[qIs51] balancer-containing parents, which are heterozygous for both oma-1 and oma-2. All other animals were the progeny of parents of the listed genotype.
c
Sterile, with a defect in meiotic maturation as described by Detwiler et al. (2001).
d
Percent embryo lethality was variable among the 12 parents analyzed; it ranged between 6 and 35%.
e
These animals lay many eggs, none of which hatch (n = 30).
f
These animals lay many eggs, some of which hatch (n = 24).
