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.

XXX progeny

Animals segregate progeny with 3 X chromosomes.

X cluster small RNA expression variant

Animals exhibit variations from controls in the expression, biogenesis, processing, or stability of the small X-chromosome derived RNAs (X cluster) species of small RNA.

diplo X gamete

Animals produce ova/sperm that contain 2 X chromosomes.

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.

nullo X gamete

Animals produce ova/sperm that contain no X chromosome in a nonmendelian segregation pattern.

X linked gene expression reduced

Levels of transcripts associated with genes on the X chromosome are decreased compared to control.

X linked gene expression enhanced

Levels of transcripts associated with genes on the X chromosome are increased compared to control.

organism X ray response variant

Animals exhibit variations in their response to X-ray radiation compared to that observed in control animals.

X ray induced mitotic germ cell arrest defective

Animals do not arrest mitotic germ cell division, as control animals, when treated with X-ray radiation.
