male turning defective

The inability of a male to properly turn during mating behavior. In C. elegans, males typically turn via a sharp ventral arch of the tail, as he approaches either the hermaphrodite head or tail.

precise vulval location variant

Any variation in the mating process that includes the male positioning his tail precisely over the vulva so that he may insert his spicules and ejaculate compared to control. In C. elegans precise vulva location (coordinating movement and tail positioning) requires the post cloacal sensillium and the spicules.

vulva location variant

Any variation in the male's ability to locate his partner's vulva when backing along the ventral side of the partner during mating compared to control. In C. elegans the male stops at the vulva, coordinates his movements to the hermaphrodite's, and positions his tail precisely over the vulva so that he may insert his spicules and ejaculate.

M lineage variant

The descendants of the M precursor cell exhibit variations in developmental programs compared to their counterparts in control animals. In C. elegans the M lineage is a postembryonic mesodermal lineage.

cell cycle arrest

Cells of the animals cease during one of its replicative phases (G1, S, G2, M).

early exit cell cycle

Cells leave the M phase (mitosis and cytokinesis) at an earlier time than sister or other control cells.

male M lineage variant

The descendants of the M precursor cell in male animals, exhibit any variation in developmental programs compared to their counterparts in control animals.

G2 checkpoint variant

Mitotic cells exhibit variations during the passage through a cell cycle control point late in the G2 phase of the mitotic cell cycle just before entry into M phase, nuclear division, compared to control cells.

hermaphrodite sex muscle morphology variant

Any variation in the form, structure or composition of the muscles of the adult hermaphrodite reproductive system compared to control. In C. elegans hermaphrodites these muscles include the vulval and uterine muscles, located near the vulva in the midbody, which all derive from the M myoblast (Wormatlas).

male sex muscle morphology variant

Any variation in the form, structure or composition of the muscles of the adult male reproductive system compared to control. In C. elegans males, the M myoblast gives rise to a much larger set of specialized muscles, compared to hermaphrodites, which differentiate within the tail region (Wormatlas).
