Maintain by mating. Hermaphrodites produce nonfunctional sperm and are fertilization defective. Self-fertility is <1% at 16C or 25C. Males are fertile.

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

Male/female strain which must be maintained by mating. spe-12(hc76) prevents self-fertility in hermaphrodites but does not impair spermatogenesis in males. Presence of him-8(e1489) increases male frequency.

Self-sterile hermaphrodites; fertile males. Mated hermaphrodites produce self and outcross progeny. Self progeny are 33% males.

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

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.

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.

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.
