(10) First, with gynandromorphs, we removed the wild-type gene long before the critical developmental events to produce large mutant clones.
(11) Next, we observed the courtship behaviors that gynandromorphs (sex mosaics) performed in response to attractive males and females.
(12) The mutant is recessive and maternal in action, producing gynandromorphs and haplo-4 mosaics among the progeny of homozygous mit females.
(13) A developmental analysis of gynandromorphic genetic mosaics shows that: (1) the gene function is autonomously essential in the eye; (2) the gene function is essential for normal development of the optic lobes; and (3) the gene function is not necessary in most major imaginal-disc cell derivatives with the exception of the eye disc.
(14) The gene claret nondisjunctional was used for the production of gynandromorphs which showed that the enhancing ability of z(a), like the eye pigment change caused by z, is autonomous.
(15) We show here that gynandromorphic females respond to pheromonal stimulation with anemotaxis.
(16) Only one was reported to be a gynandromorph; sex ratios generally have been near 1 : 1.
(17) The male tissue of this gynandromorph is hemizygous for Hk(1P), while the female tissue is heterozygous.
(18) Some interneurones in the antennal lobes of female moths that have received grafts of male antennae (gynandromorphs) respond postsynaptically to stimulation with bombykal, a major component of the pheromone.
(19) Using gynandromorph the fate map of Drosophila melanogaster blastoderm was constructed.
(20) Twenty adult cuticular structures of 1211 haploid-diploid gynandromorphs were placed on the fate map using the sturtoid calculation.
Hermaphrodite
Definition:
(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.
(a.) Including, or being of, both sexes; as, an hermaphrodite animal or flower.
Example Sentences:
(1) Several additional groups of muscle cells of more limited mass and spatial distribution include the vulval muscles of hermaphrodites, the male sex muscles, the anal-intestinal muscles, and the gonadal sheath of the hermaphrodite.
(2) These cells are also present in hermaphrodites, where they have minor structural roles in the rectum.
(3) Male sex determination in sporadic, and familial Y-ve XX males and true hermaphrodites is likely to be the result of mutation in an X-linked TDF gene and its consequent escape from the constraints of X-inactivation.
(4) Marking with feces was important in hermaphrodite-hermaphrodite interactions.
(5) We discuss the benefice of a such therapeutic option in the true hermaphroditism lately diagnosed recording to organic and psychological data.
(6) We propose that the wild-type xol-1 gene product promotes male development by ensuring that genes (or gene products) directing hermaphrodite sex determination and dosage compensation are inactive in XO animals.
(7) I don't think it is an easy thing to write and expect to be commercial, even if you are from Venus and a hermaphrodite."
(8) During induction of the Caenorhabditis elegans hermaphrodite vulva by the anchor cell of the gonad, six multipotent vulval precursor cells (VPCs) have two distinct fates: three VPCs generate the vulva and the other three VPCs generate nonspecialized hypodermis.
(9) An XX true hermaphrodite was examined for the presence of Y-specific sequences using Southern-blotting and polymerase chain reaction (PCR) techniques.
(10) The hypothesis provides an explanation for the observed bilateral asymmetry of gonadal differentiation in human hermaphrodites in terms of the bilateral asymmetry of growth of human fetal gonads.
(11) In true hermaphroditism ovarian or testicular tissue is present in the same patient; in false hermaphroditism female or male organs predominate; and in transsexualism only one way of alteration is possible i.e.
(12) The authors report the cases of two new families of true hermaphroditism (4 cases) defined by the coexistence of both testicular and ovarian tissues.
(13) A mutation in him-8 IV was identified that severely reduced recombination between the two X chromosomes in hermaphrodites and between mnDp73 and the X chromosome in males.
(14) In hermaphrodites, mnDp72 and mnDp73 promoted meiotic X nondisjunction and recombined with an X chromosome in the unc-1-dpy-3 interval at frequencies comparable to that found for X-X recombination; mnDp72(X;IV) also promoted trisomy for chromosome IV.
(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.
