WBPhenotype:0001357
|
male gonad morphology variant
|
Variations in the form or composition of a specialized tissue of the reproductive tract that produces the male gametes compared to control (Wormatlas). |
WBPhenotype:0000070
|
male tail morphology variant
|
Animals exhibit variations in the structure or organization of the somatic reproductive components of the posterior segment of the male from that observed in control males. In C. elegans, this region of the male includes the terminal canals of the reproductive tract, the digestive tract, and spicule channels along with the male specific sensilla (ray, post-cloacal, hook and spicule) and extends to the tip of the acellular fan. |
WBPhenotype:0000443
|
spicule morphology variant
|
Any variation in the appearance of the elongated sclerotized structures covered by a hardened layer of cuticle in the male tail (which are actively everted during copulation to fasten the male copulatory fan to the vulva) compared to control. |
WBPhenotype:0000963
|
male pigmentation variant
|
Males exhibit variations in the accumulation or expression of biochromes or any other substances that alter transparency/translucency of the organism compared to control animals. |
WBPhenotype:0001358
|
male nervous system morphology variant
|
Male animals exhibit variations in the structure or organization of any component that is part of the complement of organ tissues that serve to detect, relay and coordinate information about an animal's internal and external environments and to initiate and integrate its effector responses and activities, compared to that in control animals. |
WBPhenotype:0001356
|
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). |
