Tail-spike defect in all young larvae, less visible in older larvae and adults. oj55 appears to cause incomplete loss of function, as many cells fuse in postembryonic development. Homozygous males have tail and mating defects. ES=3.

how6 is a random 17 nt insertion after the eggd-2 (F58G11.3) start codon. The allele is presumably null, but at least a strong hypomorph. PGL-1::tagRFP localization in the germ line is apparently wildtype but is defective in embryos. Particularly after the first 1-2 rounds of cell division, PGL-1::tagRFP does not robustly localize to the P lineage. Strain becomes sterile over successive generations and is less fertile than wildtype. eggd-2 is also independently reported as mip-2.

how5 is a full deletion of eggd-1(C38D4.4) generated using CRISPR-Cas9. In this background PGL-1::tagRFP becomes detached from the nuclear envelope in the germ line and forms large cytoplasmic foci. PGL-1::tagRFP also does not partition efficiently to the P lineage in embryos. Strain exhibits reduced brood size and becomes sterile over successive generations at 20 C. Fertility defects are greatly exacerbated by increase in temperature. eggd-1 is also independently reported as mip-1.
