Male-hermaphrodite mating strain. Males are fertile, hermaphrodites are sterile.

Male/hermaphrodite mating strain. Hermaphrodites self-sterile at all temps, males fertile. Spermatids activate "normally" in TEA. In pronase they produce spikes but never form pseudopods. Similar to spe-12 and spe-8.

Temperature sensitive Dpy. Male/hermaphrodite mating strain. Hermaphrodites self-sterile at all temps; males fertile. Spermatids arrest with spikes in pronase; form normal pseudopods in TEA.

Temperature-sensitive. Fertile and weak Dpy at 15C. Partially fertile at 20C. Sterile at 25C. Twitcher. Spermatogenesis arrests at the spermatocyte stage.

Male/hermaphrodite mating strain. Hermaphrodites self-sterile at all temps; males fertile.

Homozygous male/hermaphrodite line. Males are fertile. Hermaphrodites are sterile, but slightly leaky producing a few progeny (at 25C - ts not tested). In pronase, spermatids from males activate to form many long spikes, terminating at this stage. A very few (1-3 per worm) activate to form normal-looking, motile spermatozoons.

Hermaphrodites are sterile; Males are fertile. Hermaphrodites lay oocytes (produce a few fertile eggs and many oocytes). Produce viable progeny when mated to males. Hermaphrodites produce 10X more self progeny at 20C (2.5/herm) than at either 16C or 25C.

Temperature sensitive spe-27 allele. Hermaphrodites are sterile at 25C but produce 30-40 progeny/hermaphrodite at 16C. Males are fertile.

Temperature sensitive spe-27 allele. Hermaphrodites sterile at 25C; hermaphrodites produce 30-40 progeny/hermaphrodite at 16C. Males cannot mate due to the unc-22 mutation. Maintain at 15C.

Unc. Leaky sterile at 20C; tighter at 16C and 25C. Easier to propagate as if male-female strain.

Dpy. spe-6(hc163) is a recessive suppressor of spe-27(it132). spe-6(hc163) also suppresses spe-8, spe-12, spe-29 and other spe-27 alleles. Causes precocious spermatid activation. Fertile between 15-25C.

Twitcher Unc. spe-6(hc163) is a recessive suppressor of spe-27(it132). spe-6(hc163) also suppresses spe-8, spe-12, spe-29 and other spe-27 alleles. Causes precocious spermatid activation. Fertile between 15-25C.

Temperature sensitive spe-27 allele. Leaky sterile at 20C. Males at 20C produce spermatids that form spikes in pronase. Males are fertile. Temperature sensitive dpy-20 allele. Maintain at 15C.

spe-6(hc163) suppresses the self-sterility of spe-29 in this strain. Self-sterile at 25C.

spe-6(hc163) suppresses hermaphrodite self-sterility of hc76. Dpy.

Dpy. spe-6(hc163) suppresses self-sterility of spe-8, spe-12, spe-27, and spe-29 mutants. Causes precocious spermatide activation. Fertile between 15-25C.

spe-6(hc163) suppresses the ts self-sterile phenotype of spe-27(it132). Also suppresses spe-8, spe-12, and spe-29. Causes precocious spermatid activation. Lays eggs and oocytes. Males are weakly fertile. Fertile between 15-25C.

Heterozygotes are WT and segregate WT heterozygote, Uncs (unc-32 homozygotes), and Steriles (dcr-1 homozygotes).

NOTE: In the referenced publication, irregularities were noted in the adr-1(gv6);adr-2(gv42) null strain, which were ascribed to background mutationsint hat strain. This strain -- adr-1(uu49);adr-2(uu28) -- was generated Crispr/Cas9 targeted mutation and phenotypes are more consistent with another null strain, adr-1(tm668);adr-2(ok735).
