(n.) An individual which has the attributes of both male and female, or which unites in itself the two sexes; an animal or plant having the parts of generation of both sexes, as when a flower contains both the stamens and pistil within the same calyx, or on the same receptacle. In some cases reproduction may take place without the union of the distinct individuals. In the animal kingdom true hermaphrodites are found only among the invertebrates. See Illust. in Appendix, under Helminths.

(15) Furthermore, the germ-line specificity of the fem-3(gf) mutant phenotype and the late temperature-sensitive period suggest that, in the wild-type XX hermaphrodite, fem-3 is negatively regulated so that the hermaphrodite stops making sperm and starts making oocytes.
(16) An unusual case of hermaphroditism in a 4 to 5-year-old roe is described.
(17) and Grassi Milano observed that when the female gonads were cultured without steroid or gonadotrophic hormones at the start of differentiation an hermaphrodite left ovary and a male right one were formed.
(18) Loss-of-function mutations in the spe-11 gene in Caenorhabditis elegans result in a paternal-effect embryonic-lethal phenotype: fertilization of wild-type oocytes by sperm from homozygous spe-11 mutant males leads to abnormal zygotic development, whereas oocytes from homozygous spe-11 hermaphrodites when fertilized by wild-type sperm develop normally.
(19) In wild-type Caenorhabditis elegans there are two sexes, self-fertilizing hermaphrodites (XX) and males (XO).
(20) Six out of 22 can transform XO animals into fertile females or hermaphrodites, whereas the remainder cause partial feminization.
Unisexual
Definition:
(a.) Having one sex only, as plants which have the male and female flowers on separate individuals, or animals in which the sexes are in separate individuals; di/cious; -- distinguished from bisexual, or hermaphrodite. See Di/cious.
Example Sentences:
(1) We examined mitochondrial DNA (mtDNA), enzyme, and morphological variation among 17 unisexual Ambystoma of hybrid origin.
(2) The levels of specific antibodies were much higher in bisexual infection than in unisexual infection and closely related to the intensity and duration of infection.
(3) Chromosomes of the Amazon molly, Poecilia formosa, a unisexual species of hybrid origin, were investigated by C-banding, silver staining, and fluorescent staining with DAPI, quinacrine dihydrochloride, and chromomycin A3.
(4) This reduction coincided with the late stages of the infection and was also observed in unisexual infection with male worms.
(5) These data, together with unisexuality, demonstrate conclusively that the all-female R. ridibunda population at Trubeschloo originated from matings between two R. esculenta.
(6) Unisexually developed males incubated for 1 h in EBSS showed both lipid accumulation and release from the dorsal surface.
(7) Skin graft evidence is used to directly identify the unisexual parent of natural hybrids produced between the bisexual species Cnemidophorus inornatus and the unisexual Cnemidophorus neomexicanus.
(8) Additional studies carried out in mice after unisexual infection revealed that egg production is not a necessary prerequisite for several of the immunologic phenomena associated with acute schistosomiasis.
(9) Further experiments were performed to determine light preferences during oviposition when unisexual and bisexual females were in direct competition.
(10) Cnemidophorus uniparens is a parthenogenetic unisexual species of lizard in which each individual develops as a female, making it a unique animal model for the study of sexual differentiation.
(11) Mice were infected with fertile bisexual Schistosoma mansoni and compared with similar animals infected with unisexual worms or sterile bisexual worms.
(12) The results revealed: (1) three unisexual grooming subgroups; (2) two focal monkeys (one female and one male) which were each avoided by five animals, one female avoided by three animals, the rest avoided by one or none; (3) that each monkey was 'friendly' with one to three others and was 'antagonistic' toward all the rest; (4) that males were socially inactive, ranked below most females, associated primarily with each other, and, in this study, were killed by females during the mating period.
(13) This confirms our previous conclusion that the evolution of the parthenogenetic mode of reproduction and expression of male-like pseudosexual behavior that are characteristic of the unisexual C. uniparens has not been accomplished by evolutionary modifications in the pattern of sex steroid hormone secretion.
