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.
