The hermaphrodite is a modified female that in the fourth larval stage makes and stores sperm to be used later to fertilize oocytes produced within the gonad of the same animal after spermatogenesis is finished. 46: 326-342. Reproductive behaviors have manifold consequences on evolutionary processes. Using serial electron microscopy synapse-level neural maps have been constructed both for adult male and hermaphrodite ( White et al., 1986; Cook et al., 2019 ).

We report that hermaphrodites of the wild-type laboratory reference strain N2 favor self-reproduction, whereas a wild isolate CB4856 (HW) favors outcrossing. C. elegans commonly exist as self-fertiliz-ing hermaphrodites, although a small percentage (<1%) of the microscopic worms are males due to altered X chromosome-au-tosomal ratios. One of two gonad arms is shown. The L2d larva retains the potential to form either a dauer larva or an L3 larva, depending on the persistence of the dauer inducing environmental parameters (Riddle, 1988). The muscle system of the male contains 41 additional sex-specific muscles (see Male-Specific Muscles). Males ("he", "him" etc.) During the dauer state, feeding is arrested indefinitely and locomotion is markedly reduced. 15492-15495, December 1998 Genetics Two functionally dependent acetylcholine subunits are encoded in a single Caenorhabditis elegans operon MILLET TREININ*,BOAZ GILLO,LILACH LIEBMAN, AND MARTIN CHALFIE* *Department of Biological Sciences, Columbia University, New York, NY 10027; and Department of Physiology and The Kuhne Minerva . Male C. elegans larvae initially display the same simple cylindrical body plan as hermaphrodites, but from the L2 stage onward, the shape of their posterior half changes as their sexual organs begin to develop (IntroFIG 5) (Sulston and Horvitz, 1977; Sulston et al., 1980; Nguyen et al., 1999). The outer tube (body wall) consists of cuticle, hypodermis, excretory system, neurons, and muscles, and the inner tube comprises the pharynx, intestine, and, in the adult, gonad. 1976. Gonadogenesis, which starts at approximately 7 hours after hatching, is completed in the L4 stage. Morphologically, dauer larvae are very thin (with a length-width ratio of about 30:1) and have a thick, altered cuticle (IntroFIG 8E and IntroFIG 8B) (see Cuticle System). The dauer state ends when the animal experiences favorable conditions. Cell and Growth Cone Migrations. The tail seam (SET) is formed.

Genetic variation in C. elegans hermaphrodite mating frequency. In the male germline, which produces only sperm, meiosis begins during L3 stage. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York. To characterize underlying neural mechanisms, we show that N2 hermaphrodites deficient in mechanosensation or chemosensation (e.g., mec-3 and osm-6 mutants) exhibit high mating frequency, implicating hermaphrodite perception of males as a requirement for low mating frequency. The nematode Caenorhabditis elegans was previously found to have the least fine-scale variation in crossover distribution among organisms studied to date.

Within the first day of the L4/adult molt, hermaphrodites accumulate fertilized eggs in the uterus; a young adult hermaphrodite will generally have a store of 10-15 eggs in its uterus at any given time.
